A bowling ball-size probe from a spaceship and a pebble-size object land on a large asteroid that is far from any star. After a long period of time has passed, it is highly probable that the pebble and the probe
 a. have each had the same change in temperature.
  b. have each had the same change in volume.
  c. are in thermal equilibrium with one another.
  d. are not in thermal equilibrium with one another.
  e. are in thermal equilibrium with one another, but are not at the same temperature.

Question 2

Two identical containers, A and B, hold equal amounts of the same ideal gas at the same Po, Vo and To. The pressure of A then decreases by a half while its volume doubles; the pressure of B doubles while its volume decreases by a half. Which statement correctly describes the temperatures of the gases after the changes?
 a. TA = 0.5TB = To.
  b. TB = 0.5TA = To.
  c. TB = TA = To.
  d. TA = 2TB = To.
  e. TB = 2TA = To.
