How much energy is needed to heat 2kh of water from 10*C to 100*C? (Water has a specific heat capacity of 4200 J/kg*C)
1. E = 2 x 4200 x (100-10). 2. = 2 x 4200 x 90 = 756 000 J.

What is the principle of the conservation of energy?
Energy can be transferred usefully from one form to another, stored or dissipated - but never created or destroyed.
8 of 10
When is energy useful?
When it can be transferred from one form to another.

Name four examples of energy transfers:
1. Electrical Devices: Electrical Energy = Light, sound and heat. 2. Batteries: Chemical Energy = Electrical and Heat 3. Electrical Generation: Kinetic = Electrical and Heat 4. Potential Energy: Elastic = Kinetic and Heat.
