Question

9 elección múltiple 1 punto what happens to particles in matter when thermal energy is absorbed? strong attractions are formed between particles. the average speed of the particles increases. the particles move closer together. the particles get larger. 10 elección múltiple 1 punto which of these describes an ideal gas? the temperature is directly related to the volume of the container. energy is lost when particles collide. particles are large compared to the volume of the container. gas particles have no attractive forces to each other or the sides of the container.

Explanation:

For question 9, when thermal energy is absorbed by matter, the kinetic energy of particles increases, which leads to an increase in their average speed. For question 10, an ideal gas is defined as a gas where particles have no attractive forces between each other or with the container walls.

Answer:

1. The average speed of the particles increases.
2. Gas particles have no attractive forces to each other or the sides of the container.
