A 20 g granite boulder absorbs 300.2 Joules of energy from the Sun, resulting in its temperature changing. Calculate this temperature change

19 °C

Explanation:

Step 1: Given and required data

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

periodic trends is an atom that gets larger as the number of electronic shells increase, the radius of atoms increases as you go down a certain group in the periodic table of elements. in general, the size of an atom will decrease as you move from left to right of a certain period.
