what is temperature?

• hot

• the degree of hotness or coldness of an object.

• cold

• Boiling water and ice cubes from the freezer

What is a thermometer?

• an instrument that measures hight

• an instrument that measures weight

• an instrument that measures temperature

What is absolute zero?

• the lowest temperature possible

• absolutely nothing

• where there's nothing left of somthing

• the highest temperature possible

What is heat?

• the transfer of potential energy from one medium or object to another, or from an energy source to a medium or object

• fire

• hot stuff radiating onto you

• the transfer of kinetic energy from one medium or object to another, or from an energy source to a medium or object

What is thermal conduction?

• water freezing

• the process of heating a pan on a stove

• ice melting

What is convection?

• when you touch a hot pan

• stirring water and making whirlpools

• process by which heat is transferred by movement of a heated fluid such as air or water

What are convection currents?

• a natural process of heat transfer involving the movement of energy and heat from one place to another

• whirlpools

• heat staying in one place at all times

• cool air and hot air mixing

What is radiation?

• hot

• an instrument that measures temperature

• a form of energy which produces sensation of warmth and flows when there is a temperature difference between two bodies

• energy that comes from a source and travels through space at the speed of light
