A tank of gas at 21 degrees C has a pressure of 1.0 atm. Using the data in the table answer the following questions. Explain your answers

A. If the tank contains carbon tetrafluoride, CF4 is the liquid state also present?

B. If the tank contains butane, C4H10 is the liquid state also present?

CF4 -128 degrees C (Boiling Point) -46 degrees C (critical Temperature) 41 atm (Critical Pressure)
C4H10 -0.5 degree C (Boling Point) 152 degrees C (Critical Temp) 38 atm (Critical Pressure)
