Specific Heat Problems

What is Specific Heat?

• The  amount of thermal energy required to increase the temperature of 1kg of a material by 1°C.
  

• The  amount of radiant energy required to increase the temperature of 1kgof a material by 1°C

• The  amount of energy required to increase the temperature of 1kgof a material by 1°C.

• The  amount of friction  required to increase the temperature of 1kgof a material by 1°C.
