Energy Released in Freezing Process

How do we calculate the energy released when water freezes?

Given data:

  • Mass of water = 565 grams
  • Latent heat of fusion of water = 334 J/g

Calculation of energy released when water freezes:

We can calculate the energy released when water freezes using the formula Q = mLf, where Q is the energy released, m is the mass of water, and Lf is the latent heat of fusion.

First, we need to plug in the values into the formula:

Q = m * Lf

Q = 565 g * 334 J/g

Calculating the energy released:

Q = 188810 J or approximately 189 kJ

Therefore, the energy released when 565 grams of water freezes is approximately 189 kJ.
