What happens to the movement of particles in colder water compared to hotter water?

Back

Particles in colder water move less than particles in hotter water.

Front

What is the relationship between a particle's speed and its energy?

Back

A particle's speed is related to how much kinetic energy it has.

Front

What is the process called when molecules turn from a liquid into a gas?

Back

Front

How do you find the mean of a set of numbers?

Back

Add up the numbers and then divide by how many you have.

Front

What is thermal energy?

Back

Thermal energy is the total kinetic energy of particles in a substance.

Front

What is the difference between conduction, convection, and radiation?

Back

Conduction is heat transfer through direct contact, convection is heat transfer through fluid movement, and radiation is heat transfer through electromagnetic waves.
