Question

What is the total amount of heat in joules required to completely melt 47 grams of ice at its melting point

Answer 1

Required heat = 15,716.8 joules

Step-by-step explanation:

Given:

Mass of ice = 47 grams

Find:

Required heat

Computation:

Required heat = Mass x latent heat of ice

Required heat = 47 x 80 caloric per gram degree

1 calories = 4.18 (Approx)

Required heat = 47 x 80 x 4.18 joules

Required heat = 15,716.8 joules
