calculate the amount of heat energy required to raise the temperature of a 5kg block of solid platinum from 0 degrees celsius to 25 degrees celsius. the specific heat of platinum is 133j/kg k. how much heat energy is required to raise 5kg of water by the same amount? the specific heat of water is 4.2kk/kg k

Question

calculate the amount of heat energy required to raise the temperature of a 5kg block of solid platinum from 0 degrees celsius to 25 degrees celsius.  the specific heat of platinum is 133j/kg k. how much heat energy is required to raise 5kg of water by the same amount? the specific heat of water is 4.2kk/kg k

drwls · Answer

Heat energy required = Q
= (Mass)*(Specific Heat)*(Temperature rise)

It is often written M*C*(delta T)

For platinum, the answer is 5*25*133 = 17,000 J (rounded to two significant figures)

Now do water.
