What is critical temperature and pressure?
For a pure substance, the critical pressure is defined as the pressure above which liquid and gas cannot coexist at any temperature. The critical temperature for a pure substance is the temperature above which the gas cannot become liquid, regardless of the applied pressure.
What is the vapor pressure of C2H6?

What phase is ethane at room temperature?
Ethane is a colorless, odorless, flammable gas.
How cold is liquid ethane?
Ethane has a much higher heat capacity than liquid nitrogen and is also liquid at temperatures just slightly above those of liquid nitrogen. Therefore, liquid ethane is cold enough (it’s melting point is -188 °C) to freeze water quickly and correctly, while not boiling off in the process.
What is the freezing point of ethane?
