Answer:
1.8 × 10² J
Explanation:
Step 1: Given data
- Mass of the rock (m): 20 g
- Initial temperature: 10 °C
- Specific heat capacity of granite (c): 0.48 J/g.°C
Step 2: Calculate the amount of heat absorbed (q)
We will use the following expression.
q = m × c × ΔT
q = 20 g × 0.48 J/g.°C × (29 °C - 10 °C) = 1.8 × 10² J
