The next four questions use this description. Our Sun has a peak emission wavelength of about 500 nm and a radius of about 700,000 km. Your dark-adapted eye has a pupil diameter of about 7 mm and can detect light intensity down to about 1.5 x 10-11 W/m2. Assume the emissivity of the Sun is equal to 1. First, given these numbers, what is the surface temperature of the Sun in Kelvin to 3 significant digits? What is the power output of the Sun in moles of watts? (in other words, take the number of watts and divide it by Avogadro's number) Assuming that all of the Sun's power is given off as 500 nm photons*, how many photons are given off by the Sun every second? Report your answer to the nearest power of 10 (e.g. if you got 7 x 1024, give your answer as 25).
When a cooked chicken breast is first removed from an oven, it has a surface temperature of 180 C. By the time the chicken is served at the table it has cooled to 120 C. What is the ratio of energy flux density emitted from the surface of the chicken when it has cooled to that when it was hot? Group of answer choices A. depends on mass of the chicken B. 0.20 C. 0.57 D. 0.67 E. depends on surface area of the chicken

At the microscopic level heat conduction is a chain of collisions by particles of different kinetic energies. Suppose a heat interaction occurs between a hot object of 80 °C and a cool object of 10 °C, and the primary energy transfer mechanism is heat conduction. If the interaction continues long enough, how will the average kinetic energy of the particles in the (initially) hot object compare to the average kinetic energy of the particles in the (initially) cool object? a. The average KE of the hot object particles will be greater than the average KE of the cool object particles. b. The average KE of the hot object particles will be the same as the average KE of the cool object particles. c. There is no way to determine the correct answer.
The enthalpy of 36 g of water vapor increases by 1830 J when its temperature increases from 150C to 175C. Assume that water vapor is an ideal gas. 1. What is the molar specific heat at constant pressure in SI units for water vapor? 2. By how much did the water vapor’s thermal energy increase? Express your answer with the appropriate units.
A manufacture claims that a teakettle has an output of 5.2kw. A test is done by heating 1liter of water. The water is initially at room temperature 22C and in 3 min the water reaches the boiling point. What can be said about the manufacture claim. I used equation P=Q/t and got q= 936kw/s. But this can't be it, I don't think. Can you help me through this problem? Thank you for your time and help.
