Answer:
45,030 joules
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
