At ordinary temperatures, the molecules of an ideal gas have only translational and rotational kinetic energies. At higher temperatures, they may also have vibrational energy. As a result, at higher temperatures

The average kinetic energy of gas molecules increases with increasing temperature.The average speed of gas molecules decreases with decreasing temperature.The temperature of a gas sample is independent of the average kinetic energy.There are gas molecules that move faster than the average.All the gas molecules in a sample cannot have the same kinetic energy.

At  31 °C, the average translational kinetic energy of a gas molecule is K. If the temperature is now increased to 59 °C, the average translational kinetic energy of a molecule, in terms of K,  will be closest to

Temperature as the average kinetic energy of a gas increases.

The average translational kinetic energy per molecule of an ideal gas at 0ºC (k =1.38 × 10–23 J/K)  is –

Which of the following statements is true?Temperature and thermal energy of the molecules are not linked.At a lower temperature, the average thermal energy of the molecules is higher.At a higher temperature, the average thermal energy of the molecules is lower.At a lower temperature, the average thermal energy of the molecules is lower.
