MCQ
Which of the following quantities is the same for all ideal gases at the same temperature?
- AThe kinetic energy of $1$ mole.
- BThe kinetic energy of $1g.$
- CThe number of molecules in $1$ mole.
- ✓Both $A$ and $C$
✓
Answer
Correct option: D.
Both $A$ and $C$
Kinetic energy per mole of an ideal gas is directly proportional to $T.$
So, it will be the same for all ideal gases.
Number of molecules in $1$ mole of an ideal is the same for all ideal gases because ideal gases obey Avogadro's law.
So, it will be the same for all ideal gases.
