Q1
In an isothermal process, the internal energy of an ideal gas:
Increases
Decreases
Remains constant
Depends on the amount of gas
For an ideal gas, the internal energy is a function of temperature. In an isothermal process, the temperature remains constant, hence the internal energy remains constant.

Q: In an isothermal process, the internal energy of an ideal gas:
Solution: For an ideal gas, the internal energy is a function of temperature. In an isothermal process, the temperature remains constant, hence the internal energy remains constant.
Steps: 4
Step 1: Understand what an isothermal process is. It is a process where the temperature of the system remains constant.
Step 2: Know that an ideal gas is a type of gas that follows certain rules, one of which is that its internal energy depends only on its temperature.
Step 3: Since the temperature does not change in an isothermal process, the internal energy of the ideal gas also does not change.
Step 4: Conclude that in an isothermal process, the internal energy of an ideal gas remains constant.
