heating and cooling

Question 1

temperature

Answer 1

temperature is what the heat level is hot or cold we use a thermometer to measure the heat we use in the uk degrees Celsius

Question 2

thermometer

Answer 2

is what we measure heat with

Question 3

conduction

Answer 3

conduction is one of the ways in which thermal energy travels
in conduction energy is transferred from one particle to the particles touching it from hotter to colder particles

Question 4

convection

Answer 4

when a gas or a liquid gets heated the particles move up

Question 5

radiation of heat

Answer 5

unlike conduction and convection which both transfer heat energy … through particles radiated heat can travel .. through a vacuum …an empty space with no particles in it

Question 6

conduction of heat in materials

Answer 6

a stone floor cold because it is a good heat conductor

a carpet feels warm because it is a poor heat conducter

Question 7

what materials are good for thermal insulation

Answer 7

glass wood plastic and air

Question 8

what is temperature measured

Answer 8

degrees Celsius

Question 9

infa-red

Answer 9

caries thermal energy from a hotter object to a cooler object

Question 10

evaporation

Answer 10

a change from liquid to gas

Question 11

expand

Answer 11

a materiel getting bigger

Question 12

change of state

Answer 12

the change od state are boiling , melting ,condensing and freezing

Question 13

what dose convection happen in

Answer 13

gases and liquids

Question 14

name a way thermal energy is transferred

Answer 14

conduction

Question 15

what happens when you cool a solid or liquid

Answer 15

it conducts because the particles vibrate less and up less

Question 16

body temp

Answer 16

37 degrees calicoes
