Can ethanol be vaporized?

In the lungs, ethanol moves by passive diffusion from the capillaries into the surrounding air sacs called alveoli. Unlike the process of active transport, passive diffusion requires no additional energy to move molecules.

#### What is vapour pressure of a liquid?

Vapour pressure is a measure of the tendency of a material to change into the gaseous or vapour state, and it increases with temperature. The temperature at which the vapour pressure at the surface of a liquid becomes equal to the pressure exerted by the surroundings is called the boiling point of the liquid.

What is vapor pressure of a liquid?

The vapor pressure of a liquid is the point at which equilibrium pressure is reached, in a closed container, between molecules leaving the liquid and going into the gaseous phase and molecules leaving the gaseous phase and entering the liquid phase.

## Is ethanol Vapour denser than air?

Ethanol has a vapor density of 1.59, which indicates that it is heavier than air.

How do you calculate total vapor pressure?

The total vapour pressure (p) is a linear function of the mole fraction xB (or xA as xA =1-xB ) because pA° and pB° are constant at a particular temperature.

### What is vapour pressure?

What is the vapour pressure of liquid?

Overview. The vapor pressure of a liquid is the point at which equilibrium pressure is reached, in a closed container, between molecules leaving the liquid and going into the gaseous phase and molecules leaving the gaseous phase and entering the liquid phase.
