Specific heat is the amount of heat per unit mass required to raise the temperature by one-degree Celsius.
Q = C × M × DT
Q = Heat Added
C = specific heat (KJ / kg°K)
M = Mass (Kg)
DT = Change in temperature (°K)
Thermal Conductivity of material indicates its ability to conduct heat. It is defined as the quantity of Heat, Q, Transmitted in time, t, through a thickness L, in a direction normal to a surfaces of area, A, due to a temperature difference DT, under steady state.
Thermal Conductivity (K) =
Heat Flow rate (Q) × distance (L)
Area (A) × Temperature difference (DT)
The unit of quantity of heat is the joule (J). Heat flow may be expressed as joules per second (J/S). Heat flow of one joule per second equals one watt (W).
For the purpose of ready identification, actual temperature levels are expressed in degree Celsius ( °C) Temperature difference (Interval or gradient) is expressed in Kelvin (K).
