Question

At constant temperature the volume of a definite mass of a gas is Inversely Proportional to Pressure is known as?

• A. Avogadro's gas law
• B. Charle's Law
• C. Boyle's Law
• D. Gay-Lussac's Law

Answer 1

The Correct Option is C

The question asks about the law that describes the relationship between the volume and pressure of a gas at constant temperature. The description matches Boyle's Law. Here's the explanation:

Boyle's Law: This law states that for a given mass of gas at constant temperature, the volume of the gas is inversely proportional to its pressure. This can be mathematically represented as:

\(P \times V = \text{constant}\) 

Where:

• P is the pressure of the gas.
• V is the volume of the gas.

This means that if the pressure increases, the volume decreases, and vice versa, as long as the temperature remains constant.

Let's rule out the other options:

• Avogadro's Gas Law: This states that equal volumes of gases, at the same temperature and pressure, contain the same number of molecules.
• Charles's Law: This law states that the volume of a gas is directly proportional to its absolute temperature at constant pressure.
• Gay-Lussac's Law: This law states that the pressure of a gas is directly proportional to its absolute temperature at constant volume.

Based on the above explanations, Boyle's Law is the correct answer as it describes the inverse relationship between volume and pressure at constant temperature.

Thus, the correct answer is Boyle's Law.
