Answer:
When heating, the temperature is increased, therefore, the average kinetic energy is increased so the molecules will start moving more rapidly.
Explanation:
Hello,
Kinetic molecular theory is based on a series of specific statements:
- Gases are constituted by a raft of particles that are considered as both hard and spherical bodies under a state of constant and random movement.
- The particles are constantly moving in a straight line until they collide to each other or against walls of the container.
- There is no force of attraction nor repulsion among gas particles or among the particles and the walls of the container.
- Collisions are said to be perfectly elastic.
- The average kinetic energy of a raft of gas particles is temperature-dependent only.
- The higher the temperature the higher the average kinetic energy of the gas and the other way around.
In such a way, considering the last two statements, when heating, the temperature is increased, therefore, the average kinetic energy is increased so the molecules will start moving more rapidly in comparison to the initial state.
Best regards.
