Which defines the average kinetic energy of a system’s particles? density pressure temperature volume

Temperature

Explanation:

The kinetic energy is proportional to the temperature. That is, temperature is a measure of the kinetic energy of atoms and molecules that are part of a system.

This can be explained by kinetic theory.

Option (c) is the correct answer.

Explanation:

Relation between kinetic energy and temperature is as follows.

As, kinetic energy is directly proportional to temperature. So, when there will be increase in temperature then there will also occur increase in kinetic energy of the particles of a substance.

Therefore, when gas particles move more slowly then it means kinetic energy of gas particles is very low. It also implies that temperature is low.

Similarly, when kinetic energy is high then there it means temperature is also high.

Thus, we can conclude that temperature defines the average kinetic energy of a system’s particles.

- calcium has greater affinity to bond with electron receptors than hydrogen does and hence, it has the ability to replace hydrogen in most of its compounds.

- lithium has 2 valence electrons in the product because it can make only 1 bond with hydrogen. beryllium has 4 valence electrons in the product because it can only make 2 bonds. it has fewer electrons than neon and can react with electron donors. each hydrogen has 2 valence electrons, the same as helium.

- the covalent bond formed between carbon and hydrogen is polar because carbon is more electronegative than hydrogen and it attracts the bonded electron pair closer to itself, thus giving hydrogen a partial positive charge.

- a hydrogen bond is a relatively weak bond that hydrogen atoms make with the electronegative atoms nitrogen, oxygen or fluorine.

so the best choice is a.) 2 calcium (ca) atoms
