This question is in reference to the first law of thermodynamics.
00:05
It states that one statement of the first law of thermodynamics is, and then it provides five statements.
00:16
The first one says the total work done on a system is equal in magnitude, but opposite in sign to the heat absorbed by the system.
00:27
So they're saying work is equal to the negative of heat.
00:33
This is not an equation for the first law of thermodynamics and not true.
00:42
The next one is the total energy change for a system is equal to the sum of the heat transferred to or from the system and the work done by or on the system suggesting the change in internal energy is equal to the sum.
01:00
To q the heat plus w the work and this one is true.
01:06
This is an example of an equation describing the first law of thermodynamics.
01:15
C says the amount of work done on a system is dependent of pathway.
01:23
Although work we think is being an extensive property where it is the function of the pathway, i don't believe that they meant you to answer this question as true because they only want you to select one...
