If I were in space, how long would it take to get hypothermia ( ΔT = -2 °C). Assume I am essentially just 70 kg of water (Csp = 4.184 J/gC) radiating as a perfect back-body radiator.

Presents the diagram of the problem, necessary formulas, clearance and numerical solution: The surface of the Sun has a temperature of about 5,800 K. The radius of the Sun is 6.96x108 m. Calculate the total energy radiated by the Sun each second. Assume the emissivity is 0.986.

Suppose you walk into a sauna that has an ambient temperature of 52.0°C. (a) Calculate the rate of heat transfer in watts to you by radiation given your skin temperature is 37.0°C, the emissivity of skin is 0.98, and the surface area of your body is 1.40 m2. W (b) If all other forms of heat transfer are balanced (the net transfer is zero), at what rate will your body temperature increase in degrees Celsius per minute if your mass is 70 kg? °C/min

The number density of gas atoms at a certain location in the space above our planet is about 0.75 × 10!1 m²³, and the pressure is 2.9 x 10- 10 Pa in this region. What is the temperature in this region, in degrees Celsius? T =
