Words and meanings to learn
variable
any factor in an experiment that can be changed, measured or kept the same
energy loss
the reduction of thermal energy from a system, often due to inefficient insulation or heat transfer
thermal energy transfer
the movement of thermal energy (heat) from a region of higher temperature to a region of lower temperature
insulator
a material that reduces the transfer of energy by conduction, convection or radiation; insulators have low thermal conductivity and are used to slow down the rate of energy transfer
cooling curve
a graph showing how the temperature of a substance changes over time as it loses thermal energy
