a) When a material is heated, the change in temperature of the material for any given amount of energy is dependent on the material’ s heat capacity. How much energy will water requirements for each 1C increase in temperature?

Question

b) On average, 1370 W of radiation heat energy is incident on 1m2 of Earth's surface from the Sun every second. Assuming 100% efficient and no energy losses, how long would it take for the Sun to heat 1 litre of water by 1oC using 1m2 of heat-absorbing material?

Answer 1

a) Q=mc(t1-t2)
