Law of conservation of energy | During a change, the Law of Conservation of Energy states that energy can neither be created nor destroyed. |
Kinetic theory of matter | The Kinetic Theory of Matter states that ALL particles that make up matter are constantly in motion |
Temperature | Temperature is a measure of the average kinetic energy of all the particles in an object |
Thermometer | an instrument used to measure temperature |
Thermal energy | Thermal Energy is the total kinetic energy of all the particles of a substance. |
Heat | In science, heat is the energy transferred from an object at higher temperature to an object at lower temperature. |
Calorie | One calorie = the amt of energy needed to raise 1 g of water by 1 ºC |
Conduction | the transfer of energy as heat through a material |
Conductor | A conductor is a material that transfers heat very well. |
Insulator | An insulator is a material that’s a poor conductor of heat. |
