c) Law of motion, Avogadro's law, Pascal's law, Dalton's law
d) Boyle's law, Charles's law, Gay-Lussac's law, Dalton's law

Answer 1

The four gas laws are Boyle's law, Charles's law, Gay-Lussac's law, and Avogadro's law. Boyle's law relates pressure and volume at constant temperature, Charles's law relates volume and temperature at constant pressure, Gay-Lussac's law relates pressure and temperature at constant volume, and Avogadro's law relates volume and the number of moles of a gas. These laws help us understand and predict the behavior of gases.

Step-by-step explanation:

The four gas laws are Boyle's law, Charles's law, Gay-Lussac's law, and Avogadro's law.

1. Boyle's law: It states that at constant temperature, the volume of a gas is inversely proportional to its pressure. Mathematically, it can be expressed as P1 * V1 = P2 * V2.
2. Charles's law: It states that at constant pressure, the volume of a gas is directly proportional to its temperature. Mathematically, it can be expressed as V1 / T1 = V2 / T2.
3. Gay-Lussac's law: It states that the pressure of a gas is directly proportional to its temperature, at constant volume. Mathematically, it can be expressed as P1 / T1 = P2 / T2.
4. Avogadro's law: It states that equal volumes of gases, at the same temperature and pressure, contain an equal number of particles (atoms, molecules, or ions). Hence, the volume of a gas is directly proportional to the number of moles of the gas. Mathematically, it can be expressed as V1 / n1 = V2 / n2.

These gas laws help us understand and predict the behavior of gases in different conditions.
