Light with a wavelength of 310 nm is incident on a metal that has a work function of 3.80 eV.
 
  What is the maximum kinetic energy that a photoelectron ejected in this process can have? (1 eV = 1.60  10-19 J, c = 3.00  108 m/s, h = 6.626  10-34 J  s)
  A) 0.62  10-19 J
  B) 0.21  10-19 J
  C) 0.36  10-19 J
  D) 0.48  10-19 J
  E) 0.33  10-19 J

Question 2

A fixed amount of an ideal monatomic gas is maintained at constant volume as it is cooled by 50 K. This feat is accomplished by removing 400 J of energy from the gas. How much work is done by the gas during this process?
 
  A) 0 J
  B) 400 J
  C) -400 J
  D) -200 J
  E) 200 J

Did you know?

Your skin wrinkles if you stay in the bathtub a long time because the outermost layer of skin (which consists of dead keratin) swells when it absorbs water. It is tightly attached to the skin below it, so it compensates for the increased area by wrinkling. This happens to the hands and feet because they have the thickest layer of dead keratin cells.
