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.

ca has a crystalline lattice with positive ions (since it is a metal, metals are positively charged) and electrons flow freely in its structure since the ca atoms have a large nuclear radius so the electrons are not tightly held, therefore the electrons can flow freely since they are not being highly attracted by the nucleus. moreover, one of the properties of metals are that they are conductors of electricity, thus proving ca is the element.
