- The escape speed from the Moon is much smaller than from Earth and is only 2.38 km/s. At what temperature would chlorine molecules (with a molecular mass equal to 70.91 g/mol) have an average speed vrms equal to the Moon's escape speed?Consider the electric force between a pair of charged particles a certain distance apart. By Coulomb's Law, if the charge on one of the particles is tripled, the force isWhen we double the temperature difference across an insulator, by what factor does the energy flow through the insulator increase?
- How many grams of steam at 100 ºC must be mixed with 200 g of water at 20 ºC in order toreach an equilibrium temperature of 50 ºC?your team is developing insulation for the interior of a spaceship for a trip to Mars. Should you focus on materials with high or low values of Cp? Why?The temperature change of 1 oF is equivalent to a temperature change of 1 oC. TRUE OR FALSE
- 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).DOWN 1. This is the term for molecules which have a slightly negative or positive sidedo fast i will 5 upvotes.
