EXERCISE 10
EXERCISE 10 (a) Examine the borderline between the solid and liquid phases of the two molecules. As pressure increases along each line, does the temperature increase or decrease? (b) Imagine a block of water ice on the ground in front of you on a below-freezing winter day. If you place a second block of water ice the same size on top of the first block, is that first block more or less likely than the second block to melt? Explain. (c) Imagine a block of dry ice - that is, frozen carbon dioxide - one on the floor of a sealed, refrigerated room where the pressure is 10 atmospheres. If a second block of the same size is placed on top of the first block, is that first block more or less likely than the second block to melt? Again, explain. |
