What are two ways that a liquid can be turned into a gas?

Vaporization of a sample of liquid is a phase transition from the liquid phase to the gas phase. There are two types of vaporization: evaporation and boiling. Evaporation occurs at temperatures below the boiling point, and occurs on the liquid’s surface.

What determines boiling point?

The temperature at which a pure organic substance changes from the liquid phase to the gas phase is known as the boiling point. A liquid’s boiling point can be determined using the capillary method, where an inverted capillary is placed in the liquid of interest and the liquid is heated.

How do you record boiling point?

mini scale

1. put a boiling stone in the mini test tube.
2. add about 1/2 inch of liquid.
3. clamp in stand in the fume hood.
4. insert thermometer into test tube with bottom of mercury bulb about 1/2 – 1 inch above the liquid.
5. carefully heat with mini bunsen burner till temperature remains constant.
6. read temperature.

When two liquids are mixed the resulting solution is found to be cooler?

When a liquid A is mixed with liquid B, the resulting solution is found to be cooler. What do you conclude about the nature of the solution? Answer: The solution shows a positive deviation.

What is ideal solution and non ideal solution?

The solution which obey Raoult’s law over the entire range of concentration are known as ideal solutions. When a solution does not obey Raoults’s law it is called as non-ideal solution.

What type of deviation from Raoult’s Law is observed when two volatile liquids A and B on mixing produce a warm solution?

negative deviation

What type of deviation is Raoult’s?

If the vapor pressure of a mixture is lower than expected from Raoult’s law, there is said to be a negative deviation. Negative deviations from Raoult’s law arise when the forces between the particles in the mixture are stronger than the mean of the forces between the particles in the pure liquids.

What type of deviation is expected from Roult’s law?

What is negative deviation from Raoult law?

Negative deviation from the law of raoult means that as opposed to the total vapour pressure of the solution, the total vapour pressure of the original liquid would be greater when both the liquids are mixed. Nitric & Water Solution.

What is the sign of ∆ mix for negative deviation?

Solution. The non-ideal solutions that do not obey Raoult’s law over the entire range of concentration and have vapour pressures lower than those predicted by Raoult’s law show a negative deviation from Raoult’s law. In case of solutions showing negative deviations, ΔmixH has a negative sign.

What is negative and positive deviation from Raoult’s Law?

The solutions which obey Raoult’s law over the entire range of concentration are known as ideal solutions. If the vapour pressure is higher, then the solution is said to exhibit positive deviation, and if it is lower, then the solution is said to exhibit negative deviation from Raoult’s law.
