Question

A window conducts 800 J per second when the inside is at $1 5^{\circ}$ C and the outside is at $- 5^{\circ}$ C. Find the inside temperature in kelvin that gives the same flow when the outside is at $- 1 8^{\circ}$ C (nearest whole number).

Answer:

275

Solution:

The difference must be $2 0^{\circ}$ C again. Inside = $- 18 + 20 = 2^{\circ}$ C = $275$ K.

The difference must be 2 0 ∘ C again. Inside = − 18 + 20 = 2 ∘ C = 275 K.
