First Law of Thermodynamics
GATE 2016
Easy
The internal energy of an ideal gas is a function of
- Atemperature and pressure
- Bvolume and pressure
- Centropy and pressure
- temperature only
Explanation
For an ideal gas, intermolecular forces are neglected, so internal energy depends only on the kinetic energy of the molecules, which is a function of temperature alone (Joule's law for ideal gases).
