# Boyle's Law !

**An interactive animation illustrating Boyle's Law. Placing more weights on the piston, squeezing the gas inside the piston. A volume-pressure graph displays the results.**

**An interactive animation of an experiment demonstrating Boyle's Law. Weights are added to a piston to compress a gas. The pressure and volume of the gas are recorded in a table and then plotted on a graph.**

**An animation plotting a graph of inverse volume against pressure to illustrate Boyle's Law. Calculating the inverse volume and then plot the results in a graph.**

**Boyle's law** states that at constant temperature for a fixed mass, the absolute pressure and the volume of a gas are inversely proportional. The **law** can also be stated in a slightly different manner, that the product of absolute pressure and volume is always constant.

For a fixed amount of an ideal gas kept at a fixed temperature, pressure and volume are inversely **proportional**. Or **Boyle's law** is a gas law, stating that the pressure and volume of a gas have an **inverse** relationship, when temperature is held constant.

This empirical relation, formulated by the physicist Robert **Boyle** in 1662, states that the pressure (p) of a given quantity of gas varies inversely with its volume (v) at constant temperature; i.e., in equation form, pv = k, a constant. The relationship was also **discovered** by the French physicist Edme Mariotte (1676).

In **Boyle's law**, the relationship between Pressure (P) and Volume (V) is analyzed. The form of **Boyle's law** is: P*V = k, where k is a constant and the Temperature is constant. In this equation the mass is constant and the temperature is constant and the air is confined to a compressible and expandable volume.

**Boyle's Law Formula**. **Boyle's law** developed by Robert **Boyle** in 1662, states that if we keep the temperature of a gas constant in a sealed container. Its pressure (P) varies inversely with its volume (V).

one mole of any gas will occupy the same volume. **BOYLE'S LAW**: PV = **k** where P = pressure, V = volume, and **k** = constant. (The temperature of the gas must be constant.)
