Students have asked these similar questions
(c) Is methane a solid, liquid, or gas at 1 atm and 0 °C?
(d) If solid methane at 1 atm is heated while the pressure is held constant, will it melt or sublime?
(e) If methane at 1 atm and 0 °C is compressed until a phase change occurs, in which state is the methane when the compression is complete?
A 5.4-L closed vessel is filled with 0.46 g of liquid ethanol. This ethanol containing closed vessel
is placed in the freezer and reaches the vapor pressure of 6.65 torr at -11 C.
(i) Is there any liquid ethanol remained in the closed vessel when the container is removed
and warmed to the temperature of 25 C? Justify your answer.
(ii) How many grams of liquid ethanol remained in the vessel at 2.0 C?
The enthalpy changes of vaporization, AH,vap of ethanol is 40.5 kJ/mol.
The molar mass of ethanol is 46.07 g/mol.
At 100.000C, the Vm of vapor water is 30.20 L/mol and that of liquid water is 0.0188 L/mol.
(a) Calculate the change in the boiling point per atm of pressure (dT/dp).
(b) Would the boiling point increase or decrease with an increase in pressure? You must provide an explanation.
