What type of energy do H2 and O2 have at the same temperature?

At the same temperature, hydrogen (H2) and oxygen (O2) primarily possess kinetic energy. This is due to the fact that temperature is a measure of the average kinetic energy of the molecules in a substance. In gases, molecules are in constant motion, moving at various speeds and colliding with one another and the walls of their container. The higher the temperature, the greater the average kinetic energy of the molecules.

While all the provided energy types are valid in different contexts, at the same temperature, kinetic energy is the key focus because it represents the energy of motion of the gas molecules. Thermal energy, which refers to the total internal energy of an object due to the kinetic energy of its molecules, is also related but typically involves the entire system rather than focusing solely on individual kinetic energy. Potential energy and chemical energy do not specifically relate to the motion of molecules at a given temperature. Thus, kinetic energy is the most appropriate choice for this question.
