Drag the red block out of the water and onto the scale to the right. Record it’s mass. Also record the level of the water while the block is removed. The mass of the block is g. When the block is removed from the water the water level is mL.

a) the particles of the chair are strongly held together.

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.
