When watching a daytime circus in a large, darkcolored tent, you sense significant heat transfer from the tent. Explain why this occurs.
Suppose you are standing a few feet away from a bonfire on a cold fall evening. Your face begins to feel hot. What is the mechanism that transfers heat from the fire to your face? (Hint: Is the air between you and the fire hotter or cooler than your face?)
(a) Cherry-red embers in a fireplace are at 850C and have an exposed area of 0.200m2 and an emissivity of 0.980. The surrounding room has a temperature of 18.0C. If 50% of the radiant energy enters the room, what is the net rate of radiant heat transfer in kilowatts? (b) Does your answer support the contention that most of the heat transfer into a room by a fireplace comes from infrared radiation?
Why are thermometers that are used in weather stations shielded from the sunshine? What does a thermometer measure if it is shielded from the sunshine and also if it is not?

Leila is building an aluminum-roofed shed in her backyard to store her garden tools. The flat roof will measure 2.0 m X 3.0 m in area during the coldest winter months when the temperature is - 10°C, but temperatures in Leila's neighborhood can reach as high as 38°C in the summer. What is the area of the roof that should stick out from the shed in the summer so that the roof just fits the structure during cold winter nights? (aaluminum = 24 × 10-6°C-1)
