Thermal Energy
The sum of kinetic energy of particles that make up an object.
What is Thermal Energy
Movement of thermal energy from a warmer object to a cooler object.
What is Heat transfer?
The average kinetic energy of the particles that make up a material.
What is temperature
stored energy (chemical, elastic, or gravitational)
What is potential energy?
Transfer of thermal energy by electromagnetic waves
What is Radiation

What is false?
This object measures temperature.
What is thermometer
How do atoms move if temperature is hotter?
What is faster and spread out?
True or False - When a material becomes heated it's atoms move faster and spread out causing it to become more dense.
