Question

A frozen steak initially has a temperature of 30°F. It is left to thaw in a room that has a temperature of 71°F. After 9 minutes, the temperature of the steak has risen to 41°F. After how many minutes will the temperature of the steak be 55°F?

Answer 1

To determine the time it will take for the frozen steak to reach a temperature of 55°F, we can use the concept of heat transfer and the equation Q = mcΔT.

Step-by-step explanation:

To determine the amount of time it will take for the frozen steak to reach a temperature of 55°F, we can use the concept of heat transfer. The equation for heat transfer is: Q = mcΔT, where Q is the heat transferred, m is the mass of the steak, c is the specific heat capacity of the steak, and ΔT is the change in temperature.

In this case, the initial temperature of the steak is 30°F and the final temperature is 55°F. We can rearrange the equation to solve for time: ΔT = Q / mc. By substituting the given values into the equation, we can solve for t, the time it will take for the steak to reach 55°F.
