The inside of a house is at 20°C on an early morning when the temperature outside is 15°C. The next morning the inside temperature is the same but the outside temperature is now 10°C. How much does the energy per unit time lost by conduction through the walls, windows, doors, etc., change for the house from the first morning to the second one?
a. Since the inside temperature stays the same, the loss is the same both days.
b. The loss doubles.
c. The loss halves.
d. The loss increases by 5/288 since we need to use the Kelvin scale for this calculation.
