9. John checked his car tire volume when the temperature outside was 80 °F. He was happy to see that the tires were inflated properly to 10 L. The temperature the next
day was a record low for the time of year he was in. He noticed that his tires all
looked sort of flat. He checked the volume again and found the volume of air was
half what it was the day before. What temperature was the record low?

answer: mercury

explanation:

intermolecular forces are the forces between molecules or particles.

there are two kinds of van der waals forces: weak london dispersion forces and stronger dipole-dipole forces.

in molecule of water there are dipole-dipole forces between negatively charged oxygen from one molecule of water and positively charger hydrogen of another molecule of water.

hydrogen bond is an electrostatic attraction between two polar groups that occurs when a hydrogen atom (h), covalently bound to a highly electronegative atom such as flourine (f), oxygen (o) and nitrogen (n) atoms.
