13. Which best describes the transition from gas to liquidy (2 points)
Energy must be removed because particles in liquid move more slowly
Energy must be added because particles in liquid move more quickly
O Energy is neither added nor removed in this phase transition
O Energy is either removed or added, depending on the type of particles

Energy must be removed because particles in liquid move more slowly. This statement best describes the transition from gas to liquid.

Option A

Explanation:

The process of transferring from gas to liquid is termed as condensation. It requires the release of energy from the gas molecules to condense them as liquid. Gas molecules inherit large amount of energy in order to move fast as the particles of gas moves faster compared to liquid.

Thus, the extra energy need to be released before converting it to liquid which has particles having less velocity of particles. So the statement describing the transition from gas to liquid is that the energy must be removed because the particles in liquid move more slowly.

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.
