Which has the highest boiling point?

The chemical element with the lowest boiling point is Helium and the element with the highest boiling point is Tungsten.

How do you know which has the highest boiling point?

The effect of increasing the pressure is to raise the boiling point. Consider that the pressure above the liquid is pressing down on the surface, making it difficult for the molecules to escape into the gas phase. The more pressure, the more energy is required, so the boiling point is higher at higher pressures.

Which solution has highest boiling point?

1 M AlCl3 solution will have the highest boiling point is because colligative properties such as elevation in boiling point is directly proportional to number of particles in solutions and AlCl3 produces highest number of particles or ions.

Which will have highest boiling point 1M glucose?

Breaking all the bonds in glucose molecules present in 1M glucose in comparison to 2M glucose. 2M glucose has a higher boiling point than 1M glucose. Thus, option A is the correct answer.

Which solution will have highest boiling point 1% glucose in water?

so 1% CaCl2 in water will shows maximum boiling point.

Which have highest boiling point 1 1% urea solution 2 1% glucose 3 1% sucrose 4 all have same boiling point?

In general salt compound will have highest boiling point on comparing to carbon molecules which burns out sooner, among the list glucose and sucrose are not salty compound as it belong to carbohydrate group. Hence Urea had highest boiling point since it belongs to salt category. Answer is Option (1) 1% urea solution.

What affects boiling point?

The boiling point of a liquid depends on temperature, atmospheric pressure, and the vapor pressure of the liquid. When the atmospheric pressure is equal to the vapor pressure of the liquid, boiling will begin.

What determines boiling point?

Boiling point is the temperature at which the vapor pressure of a chemical equals atmospheric pressure. To simply put, it measures the temperature at which a chemical boils. Similar to melting point, a higher boiling point indicates greater inter-molecular forces and therefore less vapour pressure.

Why does boiling point increase with solute?

A solvent’s vapor pressure will lower when a solute is added. This happens because of the displacement of solvent molecules by the solute. For the vapor pressure to equal the atmospheric pressure, a higher temperature is required, and a higher boiling point is observed. …

What liquids boil faster than water?

Nitrogen (N2), carbon dioxide, oxygen (O2), helium, chlorine (Cl2) and hydrogen are all familiar examples of substances that boil at much lower temperatures than water. Liquid helium has the lowest boiling point of all — about -452 degrees Fahrenheit, only 4.2 degrees Celsius above absolute zero.

Which has highest boiling point water or oil?

A: Water boils away at 100°C but oil can get much hotter.
