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
