Why is the gas phase spectrum of benzene different from the liquid phase?
Bboggan2
In the gas phase, benzene molecules act independently. Benzene molecules in the liquid phase are closer together than in the gas phase. They interact with each other and alter the molar absorptivity values. This causes the sharp peaks of the gas phase spectrum to broaden. Collisional broadening is also a factor in the liquid phase as well.

What is the significance of the stationary phase in gas chromatography?
The stationary phase is the medium that is used to react with the mobile phase. The molbile phase is sent through the column. The stationary phase is inside the column and reacts with your carrier liquid (mobile phase) which contains the sample that you want to be analyzed. Stationary phase is different for every column because you need different mediums for different tests.
Is vaporization a liquid to a gas?
yes it is transition from the liquid phase to gas phase
What is the phase of the mixture of water and salt?
Water and salt form a solution in the liquid phase.
What is the change of state from liquid to gas is called?
Vaporization of an element or compound is a phase transition from the liquid or solid phase to gas phase
What phase is liquid nitrogen in at room temperature?
Liquid nitrogen is liquid.
What makes mercury different from metal?
It is in its liquid phase at standard temperature and pressure.
What phase is it when ice melts?
Liquid phase: liquid water
How do evaporation and boiling different?
Evaporation is a phenomenon (change of phase) at the surface of a liquid and boiling involve the entire volume of the liquid.
Why is gaseous phase of ethanol preferable to liquid phase?
The liquid phase is preferable for drinks and solvents.
What phase has a fixed volume but not a fixed shape?
This phase is a liquid.
What makes Mercury different from most metals?
It is in its liquid phase at standard temperature and pressure.

Why does the thermal conductivity of benzene decrease with increasing intemperature?
In the gas phase molecules transfer momentum and energy as they collide with each other. In liquid phase molecules are close together and cannot move as freely as in the gas phase. Intermolecular attractive forces result in low values of liquid diffusion coefficients. This theorey is unsuccessful in deriving explicit expressions for thermal conducitivity and approximations must be used for engineering calculations.
Does boiling mean liquid?
Your Question sounds confusing but let me put it this way,most substances boil only in the liquid phase,but liquid and boiling are different
Is vaporization a liquid to a gas?
yes it is transition from the liquid phase to gas phase
What phase occurs after the liquid phase?
gas
What phase is liquid water?
Water can exist in three phases which are solid, liquid, and gas. So liquid water is water in the liquid phase.
