MCQ
The internal energy of a perfect gas is:
- ACompletely kinetic
- BCompletely potential
- CSum of potential and kinetic energy of the molecules
- DDifference of kinetic and potential energy of the molecules
✓
Answer
- Completely kinetic
Explanation:
In a perfect gas or an ideal gas, the atoms of molecules collide in a perfectly elastic manner. That is the intermolecular attractive forces are absent and thus the internal energy is completely kinetic.
