Question: Q: Gas particles are constantly colliding with each other and the walls of a container, and these collisions are elastic, so there is no net loss of what? Read this paragraph and choose the correct option from the provided answers: A N SW E R S 1. Gases consist of tiny particles of matter that are in constant motion. Gas particles are constantly colliding with each other and the walls of a container. These collisions are elastic; that is, there is no net loss of energy from the collisions. Gas particles are separated by large distances, with the size of a gas particle tiny compared to the distances that separate them. There are no interactive forces (i. , attraction or repulsion) between the particles of a gas. The average speed of gas particles is dependent on the temperature of the gas. Choices: - velocity - heat - temperature - energy A:
Answer: energy
