Question

An employee puts m=2.75 kg of melted ice cream at t =4.5°C into the freezer. Assuming that the ice cream freezes at t =−1.0°C, how long in seconds will it take for the ice cream to reach its freezing temperature?

Answer 1

To calculate the freezing time of melted ice cream, specific details such as the specific heat capacity of the ice cream and the rate of heat removal by the freezer are required, none of which are provided in the question.

Step-by-step explanation:

The question is asking how long it will take for 2.75 kg of melted ice cream at 4.5°C to reach its freezing temperature of −1.0°C. However, to calculate the freezing time, we would need the specific heat capacity of the ice cream and the rate at which the freezer can remove heat from the ice cream. Without this information, it is impossible to provide a precise answer. Typically in physics problems, energy transfer is calculated using the formula Q = mcΔT, where Q is the heat transferred, m is the mass, c is the specific heat capacity, and ΔT is the change in temperature. But, since the rate of heat transfer and the specific heat capacity are not given, we cannot calculate the time required for the ice cream to freeze.
