Answer :
The pressure law of an ideal gas states that, at constant temperature, the pressure of a given amount of gas is directly proportional to its volume. This means that if you increase the pressure on a gas while keeping the temperature constant, the volume of the gas will decrease. Similarly, if you decrease the pressure, the volume will increase. This relationship can be mathematically expressed as:
1. \( \frac{P_1}{V_1} = \frac{P_2}{V_2} \)
Here, P represents pressure and V represents volume. The subscripts 1 and 2 denote initial and final states, respectively.
For example, if you have a balloon filled with air at a certain pressure and then squeeze the balloon, the pressure inside the balloon will increase while the volume decreases, following the pressure law of an ideal gas.
Understanding this law is crucial in various fields, including chemistry and physics, as it helps explain the behavior of gases under different conditions and allows for predictions about how gases will respond to changes in pressure and volume.
