According to the First Law of Thermodynamics, what is the relationship between the net heat supplied to a system and the net work done by the system?
- There is no relationship between the net heat supplied and the net work done.
- The net heat supplied to the system is less than the net work done by the system.
- The net heat supplied to the system is equal to the net work done by the system. (correct)
- The net heat supplied to the system is greater than the net work done by the system.

- Heat was considered to be unrelated to work.
In the steam plant problem, what is the relationship between the specific heat supplied to the steam in the boiler ($q_{in}$) and the specific heat rejected by the system in the condenser ($q_{out}$)?
In the steam plant problem, what is the relationship between the specific heat supplied to the steam in the boiler ($q_{in}$) and the specific heat rejected by the system in the condenser ($q_{out}$)?
- $q_{in} = q_{out}$
- There is no relationship between $q_{in}$ and $q_{out}$.
- $q_{in} < q_{out}$
- $q_{in} > q_{out}$ (correct)
