a. How many times does the evaporation rate of a solid substance in vacuum increase with an increase in its temperature by n times, if the saturated vapor pressure increases by m times?
b. With an increase in the temperature of a solid substance from 300 to 600 K, its evaporation rate increased by 141 times. The saturated vapor pressure at 300 K is P₀. Determine the saturated steam pressure at 600 K.
