Q
Q: What happens to the internal energy of an ideal gas when it is compressed adiabatically?
Solution:
In an adiabatic compression, work is done on the gas, which increases its internal energy.
Steps: 6
Show Steps
Step 1: Understand what adiabatic means. Adiabatic means that no heat is exchanged with the surroundings.
Step 2: Know that when a gas is compressed, it means that the volume of the gas is decreasing.
Step 3: Realize that during compression, work is done on the gas. This means energy is being added to the gas.
Step 4: Remember that the internal energy of a gas is related to its temperature and the energy of its particles.
Step 5: Since work is done on the gas and no heat is lost, the internal energy of the gas increases.
Step 6: Conclude that in adiabatic compression, the internal energy of the ideal gas increases due to the work done on it.
