Consider a perfectly insulated cup (no
heat can leak in or out of the cup) containing
a mixture of 50 grams of ice and 50 grams of 7. water at 0◦ C. A small coffee cup heater inside
the cup allows heat to be transferred to the
ice and water mixture. Heat is transfer

When the heat is heated it will be melted of ice, why it still remain at a constant temperature of 0◦ C.

Explanation:

Solution

The heat given by the heater will be used in melting of the ice, therefore the temperature will remain the same at the degree of 0◦ C.

After the ice is fully melted, the temperature of water will begin to increase with time.
