Topics in Thermal Properties of Matter

1

1. Temperature and Heat

  • Temperature is a relative measure of hotness or coldness.
  • Heat is energy transferred between systems or between a system and its surroundings because of a temperature difference.
  • The SI unit of heat is joule and the SI unit of temperature is kelvin; degree Celsius is commonly used.
2

2. Temperature Scales and Absolute Temperature

  • The ice point and steam point of water are 0 °C and 100 °C on the Celsius scale and 32 °F and 212 °F on the Fahrenheit scale.
  • The Fahrenheit scale has 180 equal intervals between fixed points, while Celsius has 100.
  • A gas thermometer gives the same readings regardless of the gas used at low density.
3

3. Gas Laws and Molecular Behaviour

  • Boyle's law states that for a fixed mass of gas at constant temperature, pressure is inversely proportional to volume.
  • Charles' law states that for a fixed mass of gas at constant pressure, volume is directly proportional to absolute temperature.
  • These laws combine into the ideal gas equation PV = μRT.
4

4. Thermal Expansion

  • Most substances expand on heating and contract on cooling.
  • Thermal expansion may be linear, area, or volume expansion.
  • Copper expands about five times more than glass for the same temperature rise.
