Answer: Option (c) is the correct answer.
Explanation:
Energy that is acquired by the molecules of a substance due to their motion is known as kinetic energy.
For example, when we heat water in excess then it starts to boil and it changes into vapors.
Hence, when molecules of a liquid gain kinetic energy then they start to collide rapidly with each other. As a result, molecules move away from each other and there occurs decrease in force of attraction between the molecules. This leads to change of liquid state into vapor or gaseous state.
Thus, we can conclude that the statement they move fast enough to overcome the forces of attraction that hold them together, becoming a gas, best explains what happens when the kinetic energy of particles in a liquid state increases.
In ionic bonds electrons are transferred from one species to another and the electrostatic attraction between oppositely charged ions gives rise to the ionic bond.
covalent bonds are when electrons are shared between 2 atoms.
the electronegativity difference between the atoms taking part in the bond will decide if its an ionic bond or covalent bond.
if the electronegativity difference is very large then ionic bond is formed. if the electronegativity difference is very low then covalent bond is formed
the electronegativity difference between H and S is very small therefore they form a covalent bond by sharing their electrons
correct answer is
2) electrons are shared to form a covalent bond
If there was an inverse relationship between the temperature and the volume, our daily lives change because in high temperature things will contract.
<h3>What if there was an inverse relationship between the temperature and the volume?</h3>
If there was an inverse relationship between the temperature and the volume then with increasing temperature decrease occur in the volume of a substance. If this type of relationship is present in the world, the objects will contract when the temperature is high and expand when the temperature is low which make the solid materials expand at winter and contract at summer season.
So we can conclude that if there was an inverse relationship between the temperature and the volume, our daily lives change because in high temperature things will contract.

- Compounds are formed when two or more <u>elements</u> are chemically combined.
- When these elements are <u>chemically</u> combined, a new substance is formed with new chemical and physical <u>properties</u>.
- An element is a <u>pure</u> substance that cannot be separated into simpler substances by <u>physical</u> or chemical means.
- A compound is two or more elements <u>combined</u> chemically to produce a new substance.
- When two or more elements chemically combine, the compound has new properties, different from the chemical and physical properties of the <u>original</u> elements.
<h3>What is a chemical element?</h3>
A chemical element can be defined as a pure substance which comprises atoms that have the same atomic number (number of protons) in its nuclei and as such it is the primary constituent of matter.
Generally, some examples of a chemical element include the following:
- Argon.
- Sodium.
- Carbon.
- Oxygen.
- Hydrogen.
- Phosphorus
- Copper
- Aluminum
- Potassium
- Magnesium
<h3>What is a pure substance?</h3>
A pure substance can be defined as a single sample of matter that cannot be separated into other kinds of matter through the use of any physical or chemical separating technique because it has distinct chemical properties and a definite and constant composition.
