Which numerical setup can be used to calculate the heat energy required to completely melt 100. grams of H2O (S) at 0°C?

1. (100. g) (334 J/g)

1. (100. g) (334 J/g)

Explanation:

We are given;

Mass of ice at 0°C is 100 g

We are required to identify the numerical setup that will give the energy required to melt 100 g of ice at 0°

The process of converting ice at 0°C to water at 0°C is known as melting. The process does not involve any changes in water. During melting heat energy is absorbed to break the forces of attraction between molecules. The heat energy absorbed, Q is calculated by multiplying the latent heat of fusion by the mass of ice. That is;

Q = mass * latent heat of fusion

In this case;

The latent heat of fusion of water is 334 Joules/g

Therefore;

Heat absorbed, Q = 100 g * 334 J/g

= (100 g) (334J/g)

Thus, the appropriate numerical setup to calculate the heat absorbed is (100 g) (334J/g)
