Okay, so we're going to do from 1.
00:05
So for a, this is that energy cannot be created or destroyed, only transferred or transformed.
00:21
B, so this is a process in which a system expands at constant temperature reversibly.
00:37
C, this is an expansion where the system does not return to its initial state without external work.
00:52
D, so this is the total energy contained within a system.
01:08
E, so this is the sum of a system's internal energy and the product of its pressure and volume.
01:15
F, so this is the amount of heat required to raise the temperature of one more of a substance by 1 degree celsius.
01:25
G, so this is similar to f.
01:30
And h, so this is the expansion where no heat is exchanged with these surroundings.
01:43
I, so this is a expansion.
01:45
Hypothetical gas where molecules occupy negligible space and have no interactions.
01:57
2 .a.
02:01
So the description, this is a description of a system in terms of measurable properties like temperature and pressure.
02:11
B, so these are the properties that depend on the amount of matter in a system.
02:29
C, so this is a system that can exchange energy but not matter with its findings...
