What is boyle' law?

  1. The product of the pressure and the volume of an ideal gas at constant temperature is a constant

  2. The product of the pressure and the temperature of an ideal gas at constant volume is a constant

  3. The product of the pressure and the volume of a real gas at constant temperature is a constant

  4. The product of the pressure and the temperature of a real gas at constant temperature varies exponentially.

A Correct answer
Explanation

Boyle's Law (1662) states that for a fixed amount of ideal gas at constant temperature, pressure and volume are inversely proportional: P₁V₁ = P₂V₂, or PV = constant. Option B confuses volume with temperature, while C incorrectly specifies real gases.
