Boyle's Law is a fundamental concept in gas laws. It states that for a fixed amount of gas at a constant temperature, the pressure and volume are inversely proportional. In simple terms, if you increase the pressure on a gas, its volume decreases. Likewise, if you decrease the pressure, its volume increases.
The formula for Boyle's Law is: P_1V_1 = P_2V_2 where:
- P_1 and P_2 refer to the initial and final pressure respectively.
- V_1 and V_2 represent the initial and final volume.
So, applying Boyle's Law to our exercise, when you pump air into a tire or basketball, and the temperature remains constant, you observe that increasing the gas quantity leads to more gas pressure inside. At lower pressures, the material can accommodate more volume, but as pressure builds up, the capacity is checked by the material’s constraints.
