Is there no constant in Boyle's law?

Hookes law and Boyles law, EASY physics?

• can someone explain to me hookes law and boyles law? Boyles law: P1V1=P2V2 Hookes law:F=kx k=constant x=extension

• Answer:

  Hooke's Law - The weight applied to an elastic material is directly proportional to the extension that it produces, provided its within the elastic limit. Load (Newtons) = Extension (cm) * k(constant) Boyle's Law - When the volume of a gas is varied at the same temperature using the same mass of gas each time, the PRESSURE is always INVERSELY proportional to the VOLUME, i.e. doubling the volume, halves the pressure (larger volume means particles are further apart so pressure is less). You can express this using P = V/k(constant) Rearrange to give P1V1 = k So, for your new volume and pressure, the product will still be constant, so P2V2 = k Therefore, k = P1V1 = P2V2 = P3V3
