A steel cylinder containing 25 kg of CCl2 F2 in the form of liquid and vapor is set outdoors on a warm day (25 °C). What is the approximate pressure of the vapor in the cylinder? Pressure = atm

Can water stay liquid below zero degrees Celsius?

At standard temperature and pressure the molar volumes of CO2CO2 and NH3NH3 gases are 22.31 and 22.40 LL, respectively. The density of crystalline CO2CO2  at 160 KK is 1.56 g/cm3g/cm3. Calculate the molar volumes.

Study the following phase diagram of Substance X. pressure (atm) 36 18 0. 0 solid liquid 200 gas 400 temperature (K) Use this diagram to answer the following questions. Suppose a small sample of pure X is held at - 165. °C and 26.2 atm What will be the state of the sample? Suppose the temperature is held constant at -165. °C but the pressure is decreased by 18.3 atm. What will happen to the sample? ✓ (choose one) C solid liquid gas î

A 250 mL flask contains air at 1.005 atm and 24.7 °C.5 mL of ethanol is added, the flask is immediately sealed and then warmed to 95.5 °C, during which time a small amount of the ethanol vaporizes. The final pressure in the flask (stabilized at 95.5 °C) is 2.876 atm. a) What is the partial pressure of air, in the flask at 95.5 °C? b)A solution which contains 77.5 g of an unknown molecular compound in 342 g of water freezes at -5.18°C.What is the molar mass of the unknown?
