How much heat is absorbed by a 2000 kg granite boulder as energy from the sun causes its temperature to change from 6°c to 25°c?

= 30,020 kilo Joules

Explanation:

Heat absorbed is calculated using the formula;

Q = m× c×ΔT

where, Q is the amount of heat absorbed in Joules,

m is the mass of the substance

c is the specific heat capacity of the substance

ΔT is the change in temperature, (25°C - 6°c) = 19°C

Specific heat capacity of granite is 790 J/kg/K

Therefore;

Heat absorbed = 2000 kg × 19 × 790 j/Kg/K

                         = 30,020 kilo Joules
