Answer 2

45,030 joules

Step-by-step explanation:

The specific heat capacity of granite is 0.79

Mass= 3000 g

Initial temperature= 10°C

Final temperature= 29°C

Therefore the quantity of heat can be calculated as follows

Quantity of heat= mass × specific heat capacity × (final temperature-initial temperature)

= 3,000 × 0.79 × (29-10)

= 3000 × 0.79 × 19

= 45,030 joules

Hence the quantity of heat is 45,030 joules
