Recall and use the equation for the change in gravitational potential energy ΔE_p = mgΔh

Know that an increase in the temperature of an object increases its internal energy

Explain everyday applications using ideas about conduction, convection and radiation, including: (a) heating objects such as kitchen pans (b) heating a room by convection (c) measuring temperature using an infrared thermometer (d) using thermal insulation to maintain the temperature of a liquid and to reduce thermal energy transfer in buildings
