Mercury (Hg) has a normal boiling point of 356.7 °C, and a standard heat of vaporization of 59.11 kJ/mol. Determine what mass of mercury will vaporize in a closed container at 22°Cif it has a volume of 1.7 L of space above the liquid.
Without consulting entropy tables, predict the sign of Delta S for the following process and choose the correct reasoning for your prediction: N2(g, 10 atm) ----> N2(g, 1 atm). The mass of N2 remains constant.
The results of four replicate measurements were 5.4, 5.2, 5.5, and 5.2 m. Measurements were also made of the height of the tank, yielding 9.9, 9.8, and 9.6 m. Calculate the volume of the tank and the uncertainty in that volume.
