What is kinetic energy?

• the sum of particles that make up an object

• mass per unit

• energy due to motion

• energy transferred from one object to another while staying in place

What is specific heat?

• transfer of thermal energy

• energy due to motion

• The amount of heat needed to raise the temperature of a substance

• How hot it is outside

What is density?

• mass per unit volume

• the transfer of energy

• the measure of potential energy in an object

• a measure of the average kinetic energy of particles

What is temperature?

• the amount of heat needed to raise the temperature of an object

• a measure of the average kinetic energy of the particles that make up an object
