Question

Calculate the amount of energy needed to boil away 1.6 L of water that initially has a temperature of 55 °C.

Answer 1

The amount of energy needed to boil away the water at the initial temperature  is 301,248 J.

Energy required to boil the water

The amount of energy needed to boil the water at the given is calculated as follows;

Q = mcΔθ

where;

• m is mass of water

density of water = 1000 g/L

mass = density x volume

mass of water = 1000 g/L x 1.6 L = 1,600 g

Q = 1600 g x 4.184 J/g⁰C x (100⁰C - 55 ⁰C)

Q = 301,248 J
