HELP PLEASE!!!!!   How much heat is absored by by 20g granite boulder as energy from the sun causes its temperature to change from 10C to 29C (specific heat capacity of granite is 0.1 Cal/g C)

so.......here,Mass (m) = 20gChange in Temperature (ΔT) = 29C-10C                                               = 19CSpecific Heat Capacity = 0.1 cal/ g Cnow, plug the info. into the formula,specific heat capacity = quantity of heat / (mass * change in temperature)                       0.1       =  quantity of heat / (20 * 19)                       0.1       =  quantiy of heat / 380                0.1 * 380     =  quantity of heat                       38        =  quantity of heatso the granite rock boulder absorbed 38 calories of  heat energy from the sun
