Thermometer 10 of 24 when we record how high the liquid gets; what is it called? Measuring temperature 11 of 24 What hits the thermometer to get a higher temperature recording? the particles 12 of 24 what is it called when If a hot object touches a colder object the energy will move (transfer) to the colder object. a heat transfer 13 of 24 where does conduction occur? in solids 14 of 24 where does convection occur? in fluidst 15 of 24 the colder particles are slightly more what? dense 16 of 24 what do the dense colder particles do? sink to the bottom 17 of 24 what is radiation when all hot objects give off heat 18 of 24 what is insulation? when many materials do not conduct heat 19 of 24 why is insulation good for our homes? it keeps them warm 20 of 24 give two examples of insulation in homes. double glazing for windows and foam in between walls 21 of 24 where does air get trapped in the two examples above? in between the windows and in the foam 22 of 24 is air a good or bad conductor of heat and why? A bad conductor of heat because the particles are far apart 23 of 24 why are some houses painted white? to reflect the radiation from the sun 24 of 24
