Study Notes
Thermal Properties of Matter
- Thermal properties of matter include specific heat capacity, thermal conductivity, and coefficient of linear expansion
Effect of Temperature on Gas Volume
- When the temperature of a gas increases, its volume also increases (assuming constant pressure)
Thermal Conductivity of Materials
- Certain materials have high thermal conductivity, with some having the highest thermal conductivity (e.g. metals like copper and silver)
Coefficient of Linear Expansion
- The coefficient of linear expansion measures how much a material expands per unit change in temperature
