Question

gas molecules at higher temperature have more ------- than at cooler temperatures

Answer 1

Kinetic energy is the right answer

Answer 2

Answer:

At higher temperatures, gas molecules have more kinetic energy than at cooler temperatures due to the higher RMS speed of the molecules.

Explanation:

• The energy of gas molecules is the combination of rotational kinetic energy, vibrational kinetic energy, and translational kinetic energy.
• The temperature has a huge impact on the energy of gaseous molecules.

When we increase the temperature of the gas, the RMS speed of the molecules of gas also increases, so kinetic energy increases.

Molecules now collide with the container walls rapidly and with greater force. The rotational and vibrational kinetic energy also increases due to a greater level of vibrations and rotations.

Hence, at higher temperatures, gas molecules have more kinetic energy than at cooler temperatures.
