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?
The temperature inside the International Space Station (ISS) is kept at around 70F.Outside the ISS the temperature ranges from +250F (when between the Earth and thesun) and -250F (when shaded by the Earth). What are these three temperatures on theCelsius scale?
Two stars, A and B, have the same emissivity, but the radii and surface temperatures are different with RA = 0.5RB, and TA = 2TB. Assuming the temperature of space to be negligible, which star radiates the most energy per unit time?
a. Star Ab. Star Bc. Both radiate the same amount of energy per unit time.d. More information is needed in order to make a determination.

- At high noon, the Sun delivers 1 000 W to each square meter of a blacktop road. If the hot asphalt transfers energy only by radiation, what is its steady-state temperature?arrow_forward(a) Deter-nine the power of radiation from the Sun by noting that the intensity of the radiation at the distance of Earth is 1370 W/m2. Hint: That intensity will be found everywhere on a spherical surface with radius equal to that of Earth's orbit. (b) Assuring that the Sun's temperature is 5780 K and that its emissivity is 1, find its radius.arrow_forwardNuclear fusion, the energy solute of Sun, hydrogen bombs, and fusion reactors, occurs much more readily when the average kinetic energy of the atoms is high—that is, at high temperatures. Suppose you want the atoms in your fusion experiment to have average kinetic energies of 6.41014 J . What temperature is needed?arrow_forward

The patch has emissivity 0.300. The spacesuit under the patch is 0.500 cm thick, with a thermal conductivity k 0.0600 W/m , and its inner surface is at a temperature of 20.0 . What is the temperature of the patch, and what is the rate of heat loss through it? Assume the patch is so thin that its outer surface is at the same temperature as the outer surface of the spacesuit under it. Also assume the temperature of outer space is 0 K. You will get an equation that is very hand to solve in closed form, so can solve it numerically with a graphing calculator, with software, or even by trial and error with a calculator.arrow_forwardA physicist makes a cup of instant coffee and notices that, as the coffee cools, its level drops 3.00 mm in the glass cup. Show that this decrease cannot be due to thermal contraction by calculating the decrease in level if the 350 cm3 of coffee is in a 7.00-cm-diameter cup and decreases in temperature from 95.0 to 45.0 . (Most of the drop in level is actually due to escaping bubbles of air.)arrow_forward
