Question

When the gas shown in the Energy Distribution diagram is heated to ''T_(2), " what has happened? The average kinetic energy has lowered. The average kinetic energy has increased. Fewer molecules have a higher energy level. More molecules have a higher energy level. The highest energy level has decreased.

Answer 1

When a gas is heated to a higher temperature

, the average kinetic energy of the gas molecules increases. This is because temperature is directly proportional to the average kinetic energy of the molecules in a gas. As the temperature rises, more molecules will have higher energy levels, and the distribution of molecular energies will shift towards higher values.Therefore, the correct statements are:- The average kinetic energy has increased.- More molecules have a higher energy level.
