A) An increase in temperature and a decrease in external pressure increase the rate of sublimation, but the temperature should be increased carefully, since the substance may begin to melt or decompose.


B)The evaporation rate also increases with increasing temperature of the liquid and with a decrease in external pressure; if the pressure of saturated vapors at a specific temperature becomes equal to the external pressure, the evaporation passes into boiling.
