Consider a fixed amount of ideal gas that undergoes a thermodynamic process in which there is no exchange of heat.
(1) If the gas expands,
- i** what can you say about any work done on or by the gas?
- ii** what can you say about any change in its internal energy?
- iii** what happens to the temperature of the gas?
(2) If the gas is compressed,
- i** what can you say about any work done on or by the gas?
ii what can you say about any change in its internal energy?
iii what happens to the temperature of the gas?
