- We have 1lb of water at 25C in a paper cup. When you pour 30 g of boiling water into the cup, what will be the temperature of the resulting coffee-like mixture will be now. (Specific heat capacity of water is 1cal/(g*c), boiling temperature is 100C0 )What is the vrms of hydrogen on the surface of the sun if its temperature is 5.36E3 degC? What is the vrms of hydrogen on the surface of the earth if its temperature is 21.2 degC?A window has heavy curtains in front of it. At night the curtains are closed to minimise heat loss. During the day the curtains are pulled aside exposing the glass window. How much heat is lost through the 1.0 m x 1.0 m square glass window pane that is 4mm thick when the inside temperature is 20 degree C and the outside temperature is -6 C (negative 6.0) in 12 hrs? ( 1m = 100 cm) (1m = 1000mm) %3D
- 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).A blackbody measures 20 cm by 15 cm. If the temperature of the object is 2,500 K, how much energy does it emit per second?A certain furnace (essentially a blackbody) emits 300 W of power when operating at a temperature of 1 Kelvin. How much power will this furnace emit when the temperature is increase to 4 Kelvin?
