Equations of State: Example Problems

Try to solve these problems before watching the solutions in the screencasts.

Example Problem 1

A cylindrical propane tank (height = 64 cm, diameter = 32 cm) is charged with 4.5 kg of propane at 25°C. Use the Soave-Redlich-Kwong (SRK) equation of state to calculate the tank pressure.

For an additional example problem, see this screencast.
Example Problem 2

Placing dry ice in a closed bottle can be very dangerous as the solid CO2 becomes a gas and builds pressure within the bottle. For instance, what pressure would build up if 100 g of dry ice (CO2) were place in a 2L bottle and heated to 35°C? Assume all solid CO2 becomes a gas.
