Thermal Properties Of Matter
Thermal Properties of Matter
- Temperature
- Measure of average kinetic energy of particles
- Measured in °C, °F, or K
- Heat
- Transfer of thermal energy from one obj. to another -Can occur by conduction, convection, or radiation
- Specific Heat capacity
- Heat req to raise temp. 1g by 1°C
- Measured in J/g/°C
- Latent Heat
- Heat req. to change phase of substance
- Measured in J/g
- Thermal Expansion
- Increase in volume of substance as temp. increases
- Measured in cm^3/°C
- Thermal Conductivity
- Ability of sustance to transfer heat
- Measured in W/m/K
- Radiation
- Heat transfer by electromagnetic waves
- Does not need a medium
- Convection
- Heat transfer by fluid movement
- Needs medium
- Conduction
- Heat transfer by direct contact
- Needs a medium
