Answer:

They all have about the same vapor pressure.

Explanation:

The elevation of the vapor pressure is related to the elevation of the boiling point: for higher vapor pressure, the liquid will boils at a low temperature.

When a nonvolatile compound is added to the liquid, the boiling temperature increases, in an effect called ebullioscopy, and that difference of temperature can be calculated by:

ΔT = K*W*i

Where K is a constant for the liquid, W is the molality, and i is the van't Hoff factor, which depends on the dissociation of the compound.

i = dissociated particles/total particles

For the molecules compounds given, the ideal van't Hoff factor is 1.

The molality can be calculated by:

W = n1/m2

Where n1 is the number of moles of the solute and m2 is the mass of the solvent. In this case, all the solutes have the same number of moles for the same volume of the solution because they have the same concentration, so the change in temperature is the same for all of them.

Then, they all have about the same vapor pressure.

Answer:

Dispersion forces

Relative molecular mass

Explanation:

Alkanes experience only dispersion forces. Dispersion forces increase with increasevin the relative molecular mass of the compounds. Hence a higher relative molecular mass implies greater dispersion forces and a greater boiling point.

What happens to the volume of a gas in a closed container if the temperature increases, but the pressure remains the same? Why?
labwork [276]

Answer:

Volume will goes to increase.

Explanation:

The given problem will be solve through the Charles Law.

According to this law, The volume of given amount of a gas is directly proportional to its temperature at constant number of moles and pressure.

Mathematical expression:

V₁/T₁ = V₂/T₂

V₁ = Initial volume

T₁ = Initial temperature

V₂ = Final volume  

T₂ = Final temperature

So when the temperature goes to increase the volume of gas also increase. Higher temperature increase the kinetic energy and molecules move randomly every where in given space so volume increase.

Now we will put the suppose values in formula.

V₁/T₁ = V₂/T₂

V₂ = V₁T₂/T₁  

V₂ = 4.5 L × 348 K / 298 k

V₂ = 1566 L.K / 298 K

V₂ = 5.3 L

Hence prove that volume increase by increasing the temperature.
