Question

Before the ice is placed in the calorimeter, the ice is dried. Why did it need to be dry? If the ice was not dry, would the experimental value of the latent heat of fusion be higher or lower than the expected value? Explain.

Answer 1

Answer:

Explanation:

If the ice is not dried there will be water at zero degrees celsius.

This water will contribute to the final mass of the liquid but will not gain the equivalent amount of heat the ice would gain.

The initial temperature of water in the calorimeter will not drop as much thus the resulting temperature will be too high.

This will result into an experimental value that is too low
