Question 1

Temperature

Answer 1

The measure of the average kinetic energy of the particles of a substance.

Question 2

Celsius

Answer 2

The temperature scale on which water freezes at 0°C and boils at 100°C.

Question 3

Kelvin scale

Answer 3

The temperature scale on which zero is the temperature at which no more energy can be removed from matter.

Question 4

Absolute zero

Answer 4

The temperature at which no more energy can be removed from matter.

Question 5

Heat

Answer 5

The transfer of thermal energy from a warmer object to a cooler object.

Question 6

Convection

Answer 6

The transfer of thermal energy by the movement of a fluid.

Question 7

Convection currents

Answer 7

The movement of a fluid, caused by differences in temperature, that transfers heat from one part of the fluid to another.

Question 8

Radiation

Answer 8

The transfer of energy through space by electromagnetic waves

Question 9

Conduction

Answer 9

1. The transfer of thermal energy from one particle of matter to another. 2. A method of charging an object by allowing electrons to flow from one object to another object through direct contact.

Question 10

Conductor

Answer 10

1. A material that conducts heat well. 2. A material that allows electric charges to flow.

Question 11

Insulation

Answer 11

1. A material that does not conduct heat well. 2. A material that does not easily allow electric charges to flow.

Question 12

Specific heat

Answer 12

The amount of heat required to raise the temperature of 1 kilogram of a material by 1 kelvin, which is equivalent to 1°C.
