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

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.
