PhysicsBowl 2019 Q13


13) For this question, we want to find the temperature outside when we know that heat is conducted through the window of a house. We can use the rate of heat transfer to solve this problem.

Where Q is heat, t is time, k is heat transfer constant, A is area, T is temperature, and ℓ is thickness

Next, we can solve this equation for the initial temperature.

Where Q is heat, t is time, k is heat transfer constant, A is area, T is temperature, and ℓ is thickness

Finally, if we convert all our values to the correct units and plug-in our values, we will find the temperature outside.

Answer: D
