Q1: At a temperature of 0°K, the molecules of a gas have only __________ energy.A rotational
B vibrational
C translational
D none of these
ANS:C - translational At a temperature of 0 Kelvin (absolute zero), the molecules of a gas have only translational energy. Absolute zero (0 Kelvin) is the lowest possible temperature, at which molecular motion ceases entirely. At this temperature, molecules do not possess any thermal energy to engage in rotational or vibrational motion. However, they may still exhibit translational motion, meaning they can move from one point to another within their container. So, at 0 Kelvin, the molecules of a gas have only translational energy. |
