A carpenter builds a solid wood door with dimensions 2.00 m ×0.95 m × 5.0 cm. Its thermal conductivity is k = 0.120 W/(m⋅K). The air films on the inner and outer surfaces of the door have the same combined thermal resistance as an additional 2.1 cm thickness of solid wood. The inside air temperature is 15.0 ∘C, and the outside air temperature is -8.0 ∘C. What is the rate of heat flow through the door? By what factor is the heat flow increased if a window 0.550 m on a side is inserted in the door? The glass is 0.500 cm, and the glass has a thermal conductivity of 0.80 W/(m⋅K). The air films on the two sides of the glass have a total thermal resistance that is the same as an additional 12.0 cm of glass.
The basal metabolic rate is the rate at which energy is produced in the body when a person is at rest. A 75 kgkg (165 lblb) person of height 1.85 mm (6.07 ftft) would have a body surface area of approximately 2.00 m2m2. Part A What is the net amount of heat this person could radiate per second into a room at 17.0 ∘C∘C (about 62.6 ∘F∘F) if his skin's surface temperature is 31.0 ∘C∘C? (At such temperatures, nearly all the heat is infrared radiation, for which the body's emissivity is 1.0, regardless of the amount of pigment.) Express your answer with the appropriate units. HnetHnet = nothingnothing SubmitRequest Answer Part B Normally, 80%% of the energy produced by metabolism goes into heat, while the rest goes into things like pumping blood and repairing cells. Also normally, a person at rest can get rid of this excess heat just through radiation. Use your answer to part A to find this person's basal metabolic rate…
A sealed container holding 0.492 kg of liquid nitrogen at its boiling point of 77.3 K is placed in a large room at 23.2°C. Energy is transferred from the room to the nitrogen as the liquid nitrogen boils into a gas and then warms to the room's temperature. Liquid nitrogen has a latent heat of vaporization of 2.01 ✕ 105 J/kg. The specific heat of N2 gas at constant pressure is cN2 = 1.04 ✕ 103 J/kg. K (a) Assuming the room's temperature remains essentially unchanged at 23.2°C, calculate the energy (in J) transferred from the room to the nitrogen.
