What is the heat needed to raise the temperature of 24.7 kg silver from 14.0 degrees celsius to 30.0 degrees celsius? specific heat capacity of silver is 236 j/(kg * c°). 5.93 e 4 j 8.18 e 4 j 9.32 e 4 j 11.6 e 4 j 17.5 e 4 j?

The amount of heat needed to increase the temperature of a substance by  is given by

where
m is the mass of the substance
is its specific heat capacity
is the increase of temperature

The sample of silver of our problem has a mass of . Its specific heat capacity is  and the increase in temperature is


Therefore, the amount of heat needed is
