A gas at 0°C is cooled at constant pressure until its volume becomes half the original volume. The temperature of the gas at this state will be_______________?
Correct answer: A. -136.5°C
- A. -136.5°C
- B. - 136.5°K
- C. -273°C
- D. 0°K
Explanation
At constant pressure, Charles's law gives V/T = constant using absolute temperature. Halving the volume halves 273 K to 136.5 K, which is −136.5°C.
