A 36.84 g solid sample of mercury is heated from -39 oC its melting point, completely melted then heated to 96 oC, How much energy was absorbed by the sample? (Answer in kJ) S=0.14 J/goC Delta Hf = 0.011 kJ/g

The size (radius) of an oxygen molecule is about 2.0 ×10−10m. make a rough estimate of the pressure at which the finite volume of the molecules should cause noticeable deviations from ideal-gas behavior at ordinary temperatures (t= 300k ). assume that deviatons would be noticeable when volume of the gas per molecule equals the volume of the molecule itself.
