Multiple Choice

What is kinetic energy?

• Energy waiting to be used

• energy of motion

• energy that is sitting there not moving

• Energy that has the potential to move

Multiple Choice

Does the size or amount of a substance affect the boiling or freezing point?

• Yes

• No

Multiple Choice

What does temperature measure?

• the amount of particles in an substance

• the average body temperature

• the average kinetic energy of particles of an object/substance

• the total amount of kinetic energy a substance will ever have

Multiple Choice

What is the most commonly used measurement for temperature in science?

• fahrenheit

• celeius

• kelvin

Multiple Choice

Why does the bigger pot have more energy than the smaller pot?

• fewer particles to reach the boiling point

• less water to reach boiling point

• more particles therefore more energy

• they have the same amount of energy.
