Answer 1

Answer:

16 KJ  or 16,720 J energy has gained by the water.

Explanation:

Given data:

Mass of water = m = 100 g

Temperature difference = ΔT=  (60 - 20)∘C

specific heat of water 1 calorie =  c =  4.18 J

To find:

Heat absorbed by water = q=?

Formula:

q =  m . c .  ΔT

Solution:

q = (100 g) x (4.18J/g ∘C) x  (60 - 20)∘C

  = 16,720 J
