Question

1. in which state of matter do water particles have the most kinetic energy?

a) solid (ice) b) liquid (water) c) gas (steam) d) all have the same kinetic energy

1. the particles in a liquid can move past each other, allowing the liquid to take the shape of its container.

a) true b) false

1. energy is the capacity to do work or produce heat.

a) true b) false

1. kinetic energy is the energy an object possesses due to its:

a) position b) composition c) motion d) temperature

1. a ball held at the top of a hill possesses primarily:

a) kinetic energy b) potential energy c) both kinetic and potential energy equally d) neither kinetic nor potential energy

Explanation:

1. In the gas state, particles move the fastest, so water particles in steam have the most kinetic energy.
2. Liquids have particles that can slide past each other, enabling them to take the shape of their container.
3. Energy is indeed defined as the capacity to do work or produce heat.
4. Kinetic energy is related to an object's motion.
5. A ball at the top of a hill is stationary and has stored - energy due to its position, which is potential energy.

Answer:

1. c. Gas (steam)
2. a. True
3. a. True
4. c. Motion
5. b. Potential energy
