100

This type of energy is measured with temperature. 

What is Kinetic Energy

100

The three states of matter focused on most in class. 

Solid, Liquid, Gas

100

This type of heat transfer occurs when heat moves in electromagnetic waves through empty space. 

Radiation

100

The amount of heat needed to raise the temperature of a 1kg piece of material by 1 degree Celsius

specific heat

100

True or false:  The average kinetic energy of particles increases as the temperature increases. 

true

200

Movement of materials from an area of high concentration to a low concentration.

What is diffusion?

200

Changing from a gas to a liquid because of cooling. 

What is condensation? 

200

This type of heat transfer occurs when heat moves in cycles through a fluid such as gas or liquid. 

Convection

200

another term for heat

thermal energy

200

True or false:  The average kinetic energy of particles in a substance never changes.

false


300

Most materials do this when they are heated. 

What is expand? 

300

Changing from a solid to a liquid because of heating. 

What is melting? 

300

This type of heat transfer happens when something hot directly touches something cool. 

Conduction

300

These materials allow heat to move easily through them. 

thermal conductors

300

True or false:  If the same quantity of thermal energy is added to two different substances with the same mass, the substance with the lower specific heat will experience less of a temperature change. 

False

400
All things in the universe contain this. 

What is matter? 

400

This type of vaporization happens inside a liquid. 

What is boiling? 

400

During conduction, when a hot item touches a cool item, they eventually become the same temperature.  This is called: 

thermal equilibrium

400

These materials do not allow heat to travel through them easily.

Thermal insulators

400

What type of heat transfer happens when you get a sunburn during a baseball game? 

Radiation

500

The rate of diffusion speeds up when this happens to a material. 

The material is heated up. 
500

When two phases are present on a heating curve, the temperature of the material does this. 

Remains the same. 

500
Describe what happens to particles as heat is removed. 
particles slow down and come closer together
500

Tell two properties that affect how quickly something heats up. 

surface area, thickness, reflectivity, absorption, mass

500

What type of heat transfer happens when a hot-air balloon is flown? 

Convection
