Problem
A sheet of insulating foam is used to cover a hot plate. If the foam’s thickness is doubled while its area, thermal conductivity, and the temperature difference between its faces remain unchanged, by what factor does the steady-state rate of thermal energy conduction through the foam change? Explain in one sentence.
