How much heat is absorbed by a 20 g granite boulder as energy from the sun causes its temperature to change from 10°C to 29°C? (Specific heat capacity of granite is 0.1 Cal/g°C)

Asked by emilybb195

Answer (2)

so.......
here, Mass (m) = 20g Change in Temperature (ΔT) = 29C-10C = 19C Specific Heat Capacity = 0.1 cal/ g C
now, 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 heat
so the granite rock boulder absorbed 38 calories of heat energy from the sun

The granite boulder absorbed 38 calories of heat energy as its temperature increased from 10°C to 29°C. This was calculated using the formula for heat transfer with the mass of the boulder, specific heat capacity of granite, and the change in temperature. The final result shows that the heat absorbed is 38 calories.
