Why do gases generally have higher potential energy than solids?
Why does adding insulation to a hot cylinder reduce the rate at which it loses internal energy?
Which formula gives the energy required to raise the temperature of a mass m of substance with specific heat capacity c by ?T?
A pan contains 0.5 kg of water at 20 °C. How much energy is needed to heat it to 80 °C? (Take c = 4200 J/kg °C)
When a substance is undergoing a phase change at constant temperature, what happens to the internal energy?
