PRACTICE / Isochoric processes
How much does a gas warm when it cannot expand?
One mole of an ideal monatomic gas in a rigid sealed container absorbs 249 J of heat. Use R = 8.3 J mol⁻¹ K⁻¹.
Find the temperature increase.
Organize the givens & assumptions
- n = 1 mol
- Q = 249 J
- Cv = 3R/2
Only heat and pressure-volume work are considered. The gas has three active translational degrees of freedom and no change in bulk motion.
- A
- B
- C
- D
