Thermal properties of Engg. Materials:
1.Temperature:
Temperature is the degree to measure hotness and coldness.
Temperature is a physical quantity expressing hot and cold.
2.Thermal conductivity:
The rate at which heat passes through a specified material, expressed as the amount of heat that flows per unit time through a unit area with a temperature gradient of one degree per unit distance.
3.Thermal diffusivity:
Thermal conductivity of a substance divided by the product of its density and its specific heat capacity is thermal diffusivity.
4.Thermal expansion co-efficient:
Thermal expansion coefficient is the fractional increase in the linear dimension of a sample of a substance with increase in temperature at constant pressure.
5.Specific Heat capacity:
