Given :

Mass of granite , m = 20 g .

Change in temperature , \Delta T=29-10=19^oC.

Specific heat capacity of granite , C=0.79\ J/g^oC .

To Find :

The heat absorbed by granite .

Solution :

We know , heat absorb is given by :

\Delta H=mC\Delta T\\\\\Delta H=20\times 0.79 \times 19 \ J\\\\\Delta H=300.2\ J

Therefore , heat absorb is 300.2 J .

Hence , this is the required solution .
