Heat

Question 1

Temperature

Answer 1

Is the measure of the hotness or coldness of an object

Question 2

Thermometric property

Answer 2

Is any physical property that changes measurably with temperature

Question 3

Heat capacity

Answer 3

Is the energy required to change a given objects temperature by 1 Kelvin

Question 4

Specific heat capacity

Answer 4

Is the energy needed to change the temperature of 1 kg of that substance by 1 Kelvin

Question 5

Latent heat

Answer 5

Is the energy needed to change a substances state without a change in temperature

Question 6

Specific latent heat

Answer 6

Is the amount of energy needed to change the state of 1 kg of a substance without a change in temperature

Question 7

Specific latent heat of fusion

Answer 7

Is the amount of energy needed to change 1 kg of a substance from a solid to a liquid without a change in temperature (i.e at it’s melting point)

Question 8

Specific latent heat of vaporisation

Answer 8

Is the amount of energy needed to change 1 kg of a substance from a liquid to a gas without a change in temperature (i.e at it’s boiling point)

Question 9

Conduction

Answer 9

Is the movement of heat energy through a substance by the passing on of molecular vibration from molecule to molecule with no overall motion of the substance

Question 10

U-Value

Answer 10

Is the amount of heat energy conducted per second through 1m² of a structure when a temperature difference of 1° is maintained between it’s ends

Question 11

Radiation

Answer 11

Is the transfer of heat energy from one place to another if the form of electromagnetic waves without the need for a medium

Question 12

Solar constant

Answer 12

Is the average amount of the sun’s energy falling per second perpendicularly on 1m² of the Earth’s atmosphere.
It’s value is about 1.35kWm–².
It is an intensity.

Question 13

Convection

Answer 13

Is the transfer of heat through a fluid by means of circulating currents of fluid caused by the heat.
