Using appropriate equations and starting from 10°C, calculate how much the temperature of a species would have to be increased so that 1) its diffusivity in a liquid phase increases by a factor of two, and 2) its diffusivity in a gas phase increases by a factor of two. 3) Comment on the reason for the difference between the two diffusivities.
