What is Diffusion
200
A measure of the average kinetic energy of the particles in a substance
What is Temperature
200
thermal energy that is transferred from an object at a higher temperature to an object at a lower temperature
What is Heat
200
Matter is composed of particles that are _____, ______, or ______

300
The measurement for heat (remember heat is a form of energy)
What is joules
300
a liquid's particles have enough energy to escape the attractive forces of the other particles in the liquid
What is a Gaseous State
300
sum of the kinetic and potential energies of the particles in an object
What is Thermal Energy
300
Increase in the size of a substance when the temperature increases
What is Thermal Expansion
300
The rising of warmer fluid and sinking of cooler fluid
What is Convection Current
400
The Celsius to Fahrenheit conversion formula

What is Condensation & Vaporization
400
the pressure of a liquid's vapor is equal to the pressure of the atmosphere, and that liquid becomes a gas
What is The Boiling Point
400
The energy required for a liquid to change to a gas
What is Heat of Vaporization
400
The transfer of thermal energy by collisions between particles

What is Specific heat of a material
500
Consists of high-temperature gas with balanced positively and negatively charged particles
What is Plasma
500
Reduces the rate at which thermal energy flows in a material
What is Thermal Insulators
500
How are temperature and kinetic energy are related?
Temperature means the average kinetic energy of a substance, or how fast the particles are moving
500
The two things Thermal Energy depends on
