he rate at which radiant energy from the sun reaches the earth's upper atmosphere is about 1.50kW/m2. the distance from the earth to the sun is 1.50*1011 m, and the radius of the sun is 6.96x108 m. if the sun radiates as an ideal black body (e=1), what is the temperature of its surface?
A furnace is shaped like a long equilateral-triangularduct where the width of each side is 2 m. Heat is supplied fromthe base surface, whose emissivity is «1 = 0.8, at a rate of800 W/m2 while the side surfaces, whose emissivities are 0.5,are maintained at 500 K. Neglecting the end effects, determinethe temperature of the base surface. Can you treat this geometryas a two-surface enclosure?
Suppose that you intercept 5.0 * 10-3 of the energy radiated by a hot sphere that has a radius of 0.020 m, an emissivity of 0.80, and a surface temperature of 500 K. How much energy do you intercept in 2.0 min?
Suppose you want to raise the temperature of a mass m of ice from T0 < 0 °C to T > 100 °C. In this problem, represent the heat of fusion as Lf, the heat of vaporization as Lv, and the temperatures at which the phase changes occur as Tf and Tv.
