How is residence time calculated?

A beaker containing 300 ml of fine sand, has a porosity of 33%. It is slightly damp and has a saturation (S) of 0.1. S varies from 0 (zero) for completely dry material to 1 for completely saturated material.

a) What is the total void space in ml? Report your result to one decimal.

b) How much more water can be added to the damp sand get to full saturation (assuming no air gets trapped)? Report your result to one decimal.

What is the impact on the shape of the distribution for the three GEV parameters?

If the temerature of a body is heated, relative to the original emission wavelength how will the wavelength of the radiation that it emits change?
