If a liter of water is heated from 20 degrees c to 50 degrees c what happens to its volume

The volume increases by 10.3 mL.

Explanation:

This is not an easy question to answer, because water expands at different rates depending on the temperature.

However, we can use the known densities of water at these temperatures.

(a) Calculate the mass of 1 L of water at 20 °C.

The density of water at 20 °C is 0.998 20 g/mL.

(b) Calculate the volume at 50 °C.

The density of water at 50 °C is 0.988 03 g/mL.

∴ The volume increases by 10.3 mL.

vanderwaal's forces of attraction are the electrostatic intermolecular forces that exist in a molecule due to the temporary or permanent dipoles that are developed in a molecule. in , the major intermolecular forces are dipole-dipole interactions as the molecule is polar (bent structure). so the vanderwaal's forces of interaction in between molecules are the permanent dipole-dipole interactions that develop due to the dipole that exists in between the polar h - s bond. the positively charged hydrogen atom is attracted towards the negative end of the dipole that is sulfur of the adjacent molecule. therefore, these forces of attraction are relatively stronger than that of london dispersion forces that exist in non polar molecules.
