A student is using an old fashioned, hand-cranked ice cream maker. The ice cream maker works by putting ice cream ingredients into a metal canister, and then putting the canister into a wooden bucket filled with a mixture of ice and rock salt. The student then has to hand crank the handle to ensure that the ice cream freezes evenly.

Question

A student is using an old fashioned, hand-cranked ice cream maker. The ice cream maker works by putting ice cream ingredients into a metal canister, and then putting the canister into a wooden bucket filled with a mixture of ice and rock salt. The student then has to hand crank the handle to ensure that the ice cream freezes evenly.

After 25-30 minutes the ingredients become frozen ice cream. Which of the following best describes this process?

Responses
A It is endothermic because the ice and rock salt mixture absorbed heat to freeze the ice cream.It is endothermic because the ice and rock salt mixture absorbed heat to freeze the ice cream.
B It is endothermic because the ice cream absorbed cold air from the ice and rock salt mixture to freeze.It is endothermic because the ice cream absorbed cold air from the ice and rock salt mixture to freeze.
C It is exothermic because the ice and rock salt mixture absorbed heat to freeze the ice cream.It is exothermic because the ice and rock salt mixture absorbed heat to freeze the ice cream.
D It is exothermic because the ice cream absorbed cold air from the ice and rock salt mixture to freeze.

The best response to describe the process of making ice cream in an old-fashioned hand-cranked ice cream maker is:

**A: It is endothermic because the ice and rock salt mixture absorbed heat to freeze the ice cream.**

In this process, the ice and rock salt combination lowers the temperature of the surroundings, absorbing heat from the ice cream mixture, which causes the ingredients to freeze. This is an endothermic process because it requires heat to be absorbed to occur, resulting in the freezing of the ice cream.
