1-1_Matter and Energy Exam Practice

The movement of thermal energy from a warmer object to a cooler object is called:

• heat

• temperature

• kinetic energy

• entropy

In which state of matter are the particles only vibrating?

• Gas
• Liquid
• Solid
• Plasma

What are the three states of matter?

• Solid, Liquid and Gas

• Solid, Water and Oxygen

• Hard, Liquid and Air

Is rusting considered a fast or slow chemical change?

• Slow

• Fast

What happens to particles when they are heated?

• They speed up and spread out

• They slow down and move closer together

• They stop moving

• They move closer together and speed up

In a solid, the particles

• have a low amount of kinetic energy

• slide past one another

• overcome their strong attractions to each other

• move freely in any direction

Molecules in this state will change position easily and slide past one another.

This describes which phase of matter?

• Solid

• Liquid

• Gas

• potential energy

• kinetic energy

• positive energy

• solar energy
