Thermal Physics

Thermal Physics

1. Conduction: Solids, Metals, good conductors, plastics, insulators, acid structure, delocalised electrons

2. Radiation: Matt Black - Best absorber and ammitter of radiation. Silver - Best reflector, worst emitter&absorber, SLG and vaccum. Any body with thermal energy

3. Convection: Fluids (gas&liquids) Currents - Hot air/liquid rises, because it expands when it is hotter

4. Specific heat Capacity: Energy =mass,specific heat capacity, delta - change in temperature, sharing energy, energy to rise the temperature

5. Specific Latent Heat: Changing of state, SLH of vaperation - the amount of energy to turn liquid to gas, SLH Fusion - Amount of vaperation to turn liquid into a solid

6. Thermometers: Liquid in a glass, Alcohol&mercury, rise falls at delta, colder= contracts, hotter= expands, digital (temperature), Gas thermometer, uses resistance in a circuit, which is calebrated to temperature change

7. Evaperation/Changing State: The average energy decreases, faster/more energetic molecules leave in evaperation
