Asample of helium-4 behaves as an ideal gas as it isheated at
constant pressure from 294 k to 404 k. if 33 j of work isdone by
the gas during this process, what is the mass of
heliumpresent?

Use the profile illustrated for problem (1). assume that the layer of silty sand fill (sm) is placed over the entire site. estimate the thickness of the fill (h - in feet) that will cause the effective vertical stress at the center of the clay layer to increase by 517.5 pounds per square foot.
