A:Convection can happen in liquids and gases. 1 of 10 Q) What Radiation Do All Hot Objects Emitt? A:Infra-red radiation. 2 of 10 Q)What are the best absorbers of thermal radiation? A: Black,Dull Surfaces. 3 of 10 Q)What are the worst emitters of thermal radiation? A:Light, Shiny Surfaces. 4 of 10 Q)How does heat pass through a single pane of window glass? A:Heat passes through a single pane of window glass by conduction and radiation. 5 of 10 Q)What Equation Links, Energy, Mass, Specific Heat Capacity & Change In Temperate? A:Energy = mass x specific heat capacity x change in temperature. 6 of 10 Q) Can Liquids Be Compressed And Why? A:They cannot be compressed because their particles are close together. 7 of 10 Q) What Is Energy Measured in? A: Joules (J) 8 of 10 Q)Insulating a home costs £1800 and saves £50 a year. What is the payback time? A: 36 Years 9 of 10 Q)The specific heat capacity of water is 4181 J/kg/°C and that of lead is 128 J/kg/°C. This means? A:This means more energy is needed to heat water than is needed to heat the same mass of lead by the same amount. 10 of 10
