Calculate the amount of energy required (in joules) to heat 2.5 kg of water from 16.7 °C to 69.9 °C. The specific heat of water is 4.184 J/g °C.

556.5 KJ

Explanation:

We are given that

Mass of water=m=2.5 kg=

1 kg=1000 g

C

Specific heat of water=

We have to find the amount of energy required .

We know that

Using the formula

1 KJ=1000 J

Hence, the amount of energy required to heat 2.5 kg water=556.5 KJ
