this gentleman like into to the cause of the currency 1 one's mind this book that and the topic is how to express the behavior of a pure substances the federal systems consist of only a single component or correspond to the pure substance column dioxide workshop and FIL that
container in which there's only 1 kind of particles how can we describe this shows the a conjugate phase rule really exactly 2 and Kansas state variables for example of volume and temperature if you're using these 2 variables that describe staying always company all the remaining state variables of the star know the boundaries of
the 1 of which is movable put it you can just warning we also have a change in temperature and the student to his state variable freely and the max slide it's to lead me the all Gaussian can measure of fresh orange another system there 1 call dikes exact of orders for graph all we're not said to a number of different states the 1 described by a more rewarding 25 meters and temperature regarding these sessions the state has the spin of death of homogeneous single phase the pressure of 1 long it is so much for all of the 1 which changes the by keeping the capital cost will It's parties and compressing the mall you to 12 comma decimal 5 media state number 2 what has been achieved in state area with all other favorites a set for example regression just toolbox the system remains in again useful if we now increase temperature and at constant pressure to 328 2 degrees said 2 years that the volume increases to 25 they read again guess the 1st part of the compression to 12 comma decimal 5 years provided pressure fault at this stage fall this system there's a gap the fall over if that in many states of a pure substance this column diversity can work I could not be the end of the file the 1 component systems into a he chooses PDG diagram the axis of the you diagram correspond to the 3 of the variables pressure temperature and lower and state corresponds to a point and this but to wanted to will room-temperature States 3 4 at higher temperature all possible areas theory all this is the lines so called surface of the this was the the for the PG diagram is prompted to go away this is a phase diagram called 90 again this behavior is specified not by nature it's just a compilation of many many experimental things I would tell us this as scientists is to describe between them and they're not accused mathematically kind of functions and to develop theories as to why the circles of states looks just like that and he did what is that of a diagram include he he needs to face so in conditions in which a liquid and solid phases on and who's done will be long and then closed down at constant pressure 1 whopper of the negatives fair and the 8 comma decimal 5 degrees sex this the most solid and gaseous carbon dioxide coexist molecules only non formulae they told this encouraging 2 phases gas and solid of simultaneously address according to Gibbs it to face 1 component system 1 degree of freedom and so I may use in low-volume without changing temperature or pressure only the ratio solid to get changes although all warnings from 2 to 20 8 milliliters a gas phase of the period and only saw the theories meaning his face we us is not as just a block of solid carbon dioxide are also known as correct is it would come down it's like does not it's it's the the pressure of 1 bar knowledge really good fight and I so we have for example start from state ones and compress I formerly from 25 meters 294 out ML this is gonna be is they will follow if it is still part of a problem that I found really good fire and get to face system and the pressure will just 60 pops is really lost states of pollen diet find that considerably higher pressures and lower temperatures with regard to space you discussed this fall if you measure all States for all grade but in many things so come by and block them as points and all key diagram where there was a complete typical phase diagram all pure substance in this of course they if you choose discuss each time corresponds to a possible all of us they've given area or suffers in PBG's theories who's zamora's for area and exhibit some discontinuities the kings this diagram will be our common thread many of the basic principle of we the many phenomena well when dealing with phase diagrams in the middle it's useful to look 1st for the homogeneous regions which areas correspond to single face the the low volume and low temperature or characters thing for the solid state high temperatures and high volumes correspond to a homogeneous death but the temperature the warnings that includes the right a leader of homogeneous regions while the phase diagram all other regions was diagram correspond to my face between homogeneous solid I homogeneous it would region and to have faith solid liquid that all OK the nice thing that separating the homogeneous areas from these reviews once and diagram on whole by known to occur but finally here is the another vinyl the boundary of the liquid gas the king of region initial system has only 1 degree of freedom we can draw also called tired title
and their own action lines the mutual phases which coexist in who for example the Thailand runs between they to read and she will of beyond in the 2 phrase regions on this is a time of Thailand always straight lines at here and bonds and run the walls Rev. temperature constant the highlighted part used the fall can be extended this all I heard from some other bonded the two-phase regions all the time a very special time on local regular on this slide and feed him 3 phases solid liquid and gas coexist know the characteristic features the graph is the maximum of the by nodes although with that of each it looks like an inverted upside down the other this maximum scores the critical but above the critical point gas and liquid are indistinguishable of the states and our whole supercritical fluids to survive
the 3 dimensional PBG diagram all in two-dimensional approach actions on you as the projection the PV plane or projection from the P. T the process from state 1 to state fall in PGs phase diagram is a simple but could not not too long ago brush and P. the phase diagram this thing process corresponds to a discussion of the new in king 1st the pressure increases human compassion the two-phase region besides an long to sleep compression on time the role of protection local finally opened the pv diagram when projecting into the PG diagram the 2 phases majors are reduced reliance and the critical aligned comes into the Thailand are no longer the found in all its height the reviews of poems the Peachey diagram for the sake of clarity restrict our further discussion of the gas phase region hope that they died and according to I but this standard state was set to twentyfive point researchers and 1 well carbon-dioxide as against the standard state but point 1st bonds so this this that's the kind I said the model was about to let it fall point 8 legions interestingly each guesses about is more rewarding and standards yeah then the clerk the portents 3 defines the so called normal condition or no almost S. could feed that prevented to Europe agrees says his and 1 atmosphere 1 0 0 1 3 by under normal conditions the moral or even argue that is slightly lower than the standard conditions about 200 2 comma decimal 4 years some students so far for those cells states from the PDG diagram app-specific communities the past derivative of the modal logic expected temperature pressure corresponds to create which can be illustrated by the energy of in our PBG than K. we can walk in all clouds directions and experience the 2nd flight 1 red or you can look at the threats direction and maybe the difference if the pressure constant the parser derivative of the morning was suspected temperature that ethanol files directions is associated with the of expansion coefficient as well in the current level the larger if we keep can mention constant with plastic derivative of the voice respected pressures that is within the last year at the net to right corresponds to the compressibility cup the relationship between mobile pressure this people the the that fit the small volume could change the brush because model volumes of data but it didn't panel tool and only to state variables mathematically speaking molal volumes tilted at branch DDE clear impact on the team at the p the fact is that Senator from the GGNB in red and green other pasta derivative of the model like and these those 2 the expansion coefficient of and the cat to good loans that is the rise of
known about the diagram 1 component in order to describe the state of a pure substance that we need to stay there for example more volume and temperature this review a graphical representation of all possible states of a single components system we obtain a thought that all states in the PBGC this
unfit for homogeneous were common genius activity in the area the rate by by old is the real G. is areas all tied but I connect phases in equilibrium other characteristics of the phase diagram of critical points and when the critical point here and it's written out yeah well and as
part of those of the PDG circles the partial derivatives associated with the Congress ability at the time of the expansion coefficients
thank you for watching hope to see you again
