2. Mathematically Boyle's low is stated PV = PV= orP_(1)V_(1)= __

Boyle's law, also known as the Boyle–Mariotte law, states that the pressure and volume of a gas have an inverse relationship when temperature is held constant. Mathematically, Boyle's law can be expressed as:<br /><br />\[ P \times V = \text{constant} \]<br /><br />or<br /><br />\[ P_1 \times V_1 = P_2 \times V_2 \]<br /><br />where:<br />- \( P \) is the pressure of the gas,<br />- \( V \) is the volume of the gas,<br />- \( P_1 \) and \( V_1 \) are the initial pressure and volume,<br />- \( P_2 \) and \( V_2 \) are the final pressure and volume.<br /><br />This means that if the volume of the gas increases, the pressure decreases proportionally, and vice versa, provided the temperature remains constant.
