Your body may need up to 15 times more oxygen when you exercise, so you start to breathe faster and heavier. Your breathing rate will increase until the muscles surrounding the lungs just can't move any faster. This maximum capacity of oxygen use is called VO2 max. The higher the VO2 max, the more fit a person is.
London dispersion forces and dipole-dipole forces are. collectively known as van der Waals forces. Molecules can have any mix of these three kinds. of intermolecular forces, but all substances at least have London dispersion forces. London dispersion forces exist for all substances, whether composed of polar or nonpolar. molecules. They arise from the formation of temporary, instantaneous polarities across a. molecule from circulations of electrons.
covalent bonds are the strongest type of intramolecular bond and hydrogen bonds are the strongest type of intermolecular bond however intramol ecular bonds within molecules or compounds are always stronger that intermolecular bonds between molecules so covalent bonds are much stronger that hydrogen bonds 5 people found this useful
