## Essential University Physics: Volume 1 (3rd Edition)

We must find the temperature that the water will be at: $H = 4(T+15) = 4T + 60$ We see this equal to the power output of the lamp, which is 50 Watts: $50 = 4T + 60 \\ T = -2.5 ^{\circ}C$ This is below the freezing point, which is 0 degrees C, so we see that the bunny will not be able to drink the water.
