1. which can happen during a physical change? (2 points)
molecules can move more rapidly and freely and change states.
the molecules in a substance break into smaller molecules.
the molecules in a substance react with other molecules.
the molecules in a substance are destroyed.

Answer : The correct option is, Molecules can move more rapidly and freely and change states.

Explanation :

Molecules can move more rapidly and freely and change states.  

In this process, a physical change occurs due to the changes in the phase.

The molecules in a substance break into smaller molecules.

In this process, a chemical change occurs due to the formation of new compound.

The molecules in a substance react with other molecules.

In this process, a chemical change occurs because when a molecule react with another molecule it gives new compound.

The molecules in a substance are destroyed.

In this process, a chemical change occurs due to the decomposition of molecule to give a new compound.

Hence, the correct option is, Molecules can move more rapidly and freely and change states.
