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
