1. You have ice at 263 K (-10.0 °C) and 1.0 atm. What could you do to make the ice
sublime?
2. A sample of dry ice (solid CO2) is cooled to 173 K (-100.0 °C), and is set on a table at
room temperature (298 K; 25 °C). At what temperature is the rate of sublimation and
deposition the same (assume that pressure is held constant at 1 atm)?
