Which of the following describes what occurs as a liquid becomes a solid? (5 points)

a physical change occurs; the particles of the liquid vibrate faster and their kinetic energy increases.

a physical change occurs; the particles of the liquid vibrate more slowly and their kinetic energy decreases.

a chemical change occurs; the particles of the liquid vibrate faster and their kinetic energy increases.

a chemical change occurs; the particles of the liquid vibrate more slowly and their kinetic energy decreases.

A physical change occurs; the particles of the liquid vibrate faster and their kinetic energy increases.

Explanation:

As you know when a liquid becomes a solid the particles in the liquid vibrate faster, and with more vibration and with more movement in th eparticles, the kinetic energy increases, and because of that the volume also increases, solids increase their volume contrary to liquids, that is why the answer is the first option.

r just means there's a number of carbon in teh chain. for example rcooh means that after x number of carbon, the chain ends with cooh.

explanation:

it means there are 3 atoms of oxygen
