Question

The specific heat of water is 4.186 J g-1 °C-1. What is the amount of energy, in J, required to heat 10.00 g of water 20.00 °C?

Answer 1

Answer:

Required heat q = 0.8372 j

Explanation:

Given:

Specific heat of water = 4.186 J g-1 °C-1

Mass m = 10 g = 0.01 kg

Temperature t = 20.00 °C

Find:

Required heat q

Computation:

q = cmΔT

Required heat q = [4.186][0.01][20]

Required heat q = 0.8372 j
