The hotter the substance the more ____________ in the material vibrate.

Atoms
Materials that conduct heat well are known as _____

Conductors
Newton’s law of ___________ states that the bigger the difference in temperature between two objects the faster the objects will cool or warm up.
cooling
When heating occurs by currents in a fluid it is being transferred through ________.

Convection
_________ are poor conductors as they delay the transfer of heat.

Insulators
__________ and gases, in general, are good insulators.
Liquids
As air and liquid heat up they _______________.

expand
As air and liquids cool down they ___________.

contract
___________ is when heat is transferred between different materials that are in direct contact

Conduction
__________ radiation is energy that the Earth radiates.

Terrestrial
Objects at low temperatures emit ____________.

Long waves
__________ rising is an example of convection.
Igloos are good insulators, because the snow that you use to make the igloo has a lot of _________ pockets
air
A good absorber of energy is a good ___________ of energy.

emitter
_______________ effect is the result of short wave radiation entering earth’s atmosphere, and not being able to leave the earth’s atmosphere because of its change into long wave radiation.

Greenhouse
Liquids and __________, in general, are good insulators.

Gases
A poor absorber of energy has ____________ appearance.

Light Colored
__________ is any energy, including heat, that is transmitted by radiation.

radiant energy
____________ are created when cool air rushes in to replace warm air that is rising

winds
Objects at high temperature emit __________.
Absorber
__________ can travel through empty space between our atmosphere and the sun.
___________ is energy transmitted by electromagnetic waves.

Radiation
