to calculate the temperature change. Use the heat of fusion for water to calculate "q"

is the drop in the water temperature.

Explanation:

Given:

Assuming the initial temperature of the ice to be 0° C.

Apply the conservation of energy:

Now from the heat equation:

......................(1)

where:

latent heat of fusion of ice

specific heat of water

change in temperature

Putting values in eq. (1):

is the drop in the water temperature.

the closer the planet is to the sun, the larger the gravity
