Question

A 20 g granite boulder absorbs 300.2 Joules of energy from the Sun, resulting in its temperature

Answer 1

Answer:

19 °C

Explanation:

Step 1: Given and required data

• Mass of granite (m): 20 g

• Heat absorbed (Q): 300. 2 J

• Specific heat capacity of granite (c): 0.790 J/g.°C

Step 2: Calculate the temperature change (ΔT)

We will use the following expression.

Q = c × m × ΔT

ΔT = Q/c × m

ΔT = 300.2 J/(0.790 J/g.°C) × 20 g = 19 °C
