Why is it that formula DeltaU=nCVDeltaT only applicable to ideal gas?
Accepted Answer
The formula DeltaU=nCVDeltaT is only applicable to ideal gases because it assumes that the gas particles have no interactions with each other and that their volume is negligible. In reality, gas particles do interact with each other and have a non-zero volume, which can lead to deviations from the ideal gas law. For example, at high pressures, gas particles are more likely to interact with each other, which can lead to an increase in the internal energy of the gas. Similarly, at low temperatures, gas particles have a smaller volume, which can lead to a decrease in the internal energy of the gas.
