A gas at 0°C was subjected to constant pressure cooling until its volume became half the original volume. The temperature of the gas at this stage will be________________?
Correct answer: C. -136.5°C
- A. 0°C
- B. 0°K
- C. -136.5°C
- D. -136.5°K
Explanation
At constant pressure, Charles's law states that volume is proportional to absolute temperature. Halving the volume halves 273 K to 136.5 K, which is −136.5°C, option c.
