How much heat is absorbed by 20g granite boulder as energy from the sun causes its temperature to chage from 10C to 29 c (Specific heat capital of granite is 0.1 cal C

Q = 266 Joules

Explanation:

Given the following data;

Mass = 20g

Initial temperature = 10°C

Final temperature = 29°C

Specific heat capacity of granite = 0.1 Cal/g°C to J/g°C = 0.7J/g°C

To find the quantity of heat absorbed;

Heat capacity is given by the formula;

Where;

Q represents the heat capacity or quantity of heat.

m represents the mass of an object.

c represents the specific heat capacity of water.

dt represents the change in temperature.

Substituting into the equation, we have;

Q = 20*0.7*(29-10)

Q = 14 * 19

Q = 266 Joules
