heat and temperature

Question 1

temperature

Answer 1

a measure of the hotness or coldness of a body

Question 2

thermometric properties

Answer 2

any physical properties that change measurably with temperature

Question 3

specific heat capacity

Answer 3

the heat energy needed to change the temperature of 1kg of a substance by 1K

Question 4

specific latent heat

Answer 4

the amount of heat energy needed to change the state of 1kg of that substance without changing its temperature

Question 5

conduction

Answer 5

the movement of heat energy through a substance by the passing on of molecular vibration from molecule to molecule (there is no overall motion of the substance)

Question 6

convection

Answer 6

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

Question 7

radiation

Answer 7

the transfer of heat energy from one place to another in the form of electromagnetic waves

Question 8
