Question : 29

Total: 48

Solution:

Concept:

-273^\circ\mathrm{C}

, which is absolute zero, the average kinetic energy of gas molecules becomes zero.

Explanation:

For an ideal gas confined at constant volume, pressure is directly proportional to absolute temperature:

P \propto T

At absolute zero,

T = 0\ \mathrm{K}

, so the pressure of an ideal gas drops to zero.

Answer:

B. It will drop to zero.
