Topics in Thermal Energy

1

Heat and Temperature

  • Thermal energy is a form of energy and its SI unit is joule (J).
  • Heat can do work; steam engines used this property to convert heat energy into mechanical work.
  • Work done against friction is always converted into heat.
2

Thermometers and Temperature Scales

  • Clinical thermometer is used by doctors to measure human body temperature.
  • Laboratory thermometer is used in science experiments.
  • Maximum-minimum thermometer is used by meteorologists to find daily maximum and minimum temperature.
3

Latent Heat and Change of State

  • When a substance changes state, its temperature remains constant during the change.
  • Melting point is the constant temperature at which a solid changes into liquid.
  • Boiling point is the constant temperature at which a liquid changes into vapour.
4

Thermal Expansion

  • Every material except water expands on heating from 0°C to 4°C.
  • Water is an exception because it contracts on heating from 0°C to 4°C.
  • Thermal expansion is the increase in size of a body on heating.
