Application of Specific Heat in Real World Circumstances

By Evan Pugh
What is Specific Heat?
The measure of the heat required to raise the temperature of the unit mass of a given substance by a given amount.
Grams/Kilograms
Celsius/Kelvin
How Is This Useful?
Energy (Joules)
Mass (kg/g)
Specific heat capacity (J/g/k)
Change in temperature (
/K)
