Energy Transfer by Heating Crossword Puzzle

QUESTIONS LIST:

• absorb : to soak up or take in – for waves, it is when the wave disappears as the energy it is carried is transferred to a material.
• black body radiation : the radiation emitted by a perfect black body (a body that absorbs all the radiation that hits it).
• conduction : the way energy is transferred through solids by heating. vibrations are passed on from particle to particle.
• convection : circulation of a liquid or gas (fluid) caused by increasing its thermal energy.
• emit : to give out.
• fluid : liquid or a gas.
• infrared radiation : electromagnetic waves between visible light and microwaves in the electromagnetic spectrum.
• specific heat capacity : energy needed to raise the temperature of 1kg of a substance by 1°c.
• thermal conductivity : property of a material that determines the energy transfer through it by conduction.
• thermal conductor : a material that allows energy to be transferred through it easily by heating.
• thermal insulator : a material that does not allow energy to be transferred through it easily by heating.
