Thermal Physics

1
Thermal Physics

• Heat Physics

2
Internal Energy

• Internal Energy of a system equals the sum of a
  random distribution of kinetic and potential
  energies associated with the molecules of the
  system.

3
Temperature Rise

• A rise in internal energy of body will result in
  a higher temperature.

4
Kelvin Scale

• There is an absolute scale of temperature which
  does not depend upon the physical property of any
  particular substance.
• On the thermodynamic scale (Kelvin), absolute
  zero is at that temperature at which all
  substances have a minimum internal energy.

5
Thermodynamic Scale

• 1 Kelvin 1 degree Celsius
• 0 Kelvin -273 degree Celsius
• 273 Kelvin 0 degree Celsius
• 373 Kelvin 100 degree Celsius
