m = mass of granite boulder = 20 g

c = specific heat of granite boulder = 0.79 J/gC

T₀ = initial temperature of granite boulder = 10 °C

T = final temperature of granite boulder = 29 °C

Q = heat gained by granite boulder as energy from the sun

heat gained by granite boulder is given as

Q = m c (T - T₀)

inserting the values

Q = (20) (0.79) (29 - 10)

Q = 300.2 J
