Physical properties are used to classify and compare substances. Physical properties can include density, thermal conductivity, electrical conductivity,
solubility, magnetism, melting point, and boiling point. Which statement is
correct about all of these physical properties?
They involve a change in the state of matter.
They involve the production of new substances.
They can be measured only after a change in state.
They are independent of the amount of the sample present.

Physical properties involve a change in the state of matter.

Explanation:

A chemical change would change the chemical composition.

A physical change would change the state of matter, for example solid to liquid to gas are changes in state. So, this means when water changes states of matter it is a physical change.

"hydrogen bonding is the attraction of h atoms in the water molecule (slight + charge) to o atoms in a neighboring water molecule (slight - charge); it is a weak interatomic force. but it is still strong enough to the water molecules "stick" together."
