    Two neighbors return from Florida to find their houses at a frigid 35 ∘F. Each house has a furnace that can supply 100000 Btu/h. One house is made of stone and weighs 75 tons. The other is wood and weighs 15 tons.

    How long does it take the stone house to reach 65 ∘F? Neglect heat loss, and assume the entire house mass reaches a uniform temperature.

    Tstone = _____ hours

    How long does it take the wood house to reach 65 ∘F?

    Twood = _____ hours

    EDIT: Solved, answers are 9 and 3.
