Q

Radiant energy

A

The transfer of heat energy

16
Q

Radiation

A

The transfer of heat energy in the form of electrical energy

17
Q

Heat and temperature

A

Temperature-kinetic energy of particles
Thermal energy- K.E of molecules or atoms
Heat- thermal energy that flows from temp. To lower temp.

18
Q

Heat capacity

A

Specific heat capacity joules of heat needed to raise the temp of 1g of a substance
Water has a very high spec. Heat, so it heats up slowly and cools down slowly
If heat is absorbed by a substance Q is warmer
If heat is lost by a substance Q is negative

19
Q

Phases of matter

A

Solid definite shape definite volume
Liquid definite volume no definite shape
Gas no definite shape or volume

20
Q

Phase changes

A

When solids and liquids are heated, eventually they gain enough energy to overcome the bonds
During phase changes the temperature of the substance does not change
