What has a lower boiling point?

What makes something have a low boiling point?

Explanation. There are intermolecular forces between small molecules. Intermolecular forces are much weaker than the strong covalent bonds in molecules. … Relatively little energy is needed to overcome the intermolecular forces, so small molecular substances have low melting and boiling points.

What element has the lowest boiling point highest?

Helium has the lowest boiling point of all the elements at –452.074°F (–268.93°C) followed by hydrogen –423.16°F (–252.87°C). According to the CRC Handbook of Chemistry and Physics, the highest boiling point for an element is that of rhenium 10,104.8°F (5,596°C) followed by tungsten 10,031°F (5,555°C).

What has the highest boiling point?

Carbon has the highest melting point at 3823 K (3550 C) and Rhenium has the highest boiling point at 5870 K (5594 C).

What is the relationship between volatility and boiling point?

Volatile liquids have low boiling points. A liquid with a low boiling point will begin to boil faster than liquids with higher boiling points. Much less energy (in the form of heat) is required to break the intermolecular bonds of a volatile liquid than those of liquids having higher boiling points.

How does temperature affect boiling point?

The higher the vapor pressure of a liquid at a given temperature, the lower the normal boiling point (i.e., the boiling point at atmospheric pressure) of the liquid. … The critical point of a liquid is the highest temperature (and pressure) it will actually boil at. See also Vapour pressure of water.

Which substance has the highest melting and boiling points?

The chemical element with the highest melting point is tungsten, at 3,414 °C (6,177 °F; 3,687 K); this property makes tungsten excellent for use as electrical filaments in incandescent lamps.

What are the strongest to weakest intermolecular forces?

Intermolecular forces In the order of weakest to strongest:

• dispersion force.
• Dipole-dipole force.
• Hydrogen bond.
• Ion-dipole force.
