=Volume, Pressure and Temperature=

Volume,pressure and temperature are the __macroscopic (large-scale) properties.__ The pressure, volume and temperature of a gas are inter-related. These properties also depend on the amount of gas present. If you want to find out the connection between them, the amount of the gas needs to be fixed.

A sealed balloon contains a fixed amount of gas. Its volume increases when it is placed in warm water and the temperature rises, but the pressure changes as well. We need to keep the amount of gas contant and one of the other properties constant (pressure, volume or temperature).



=Boyle's law=

Boyle's law states that:

//For a fixed mass of ideal gas at fixed temperature, the product of pressure and volume is a constant.

//

Gases have various properties which we can observe with our senses, including the gas pressure, temperature, mass, and the volume which contains the gas.

In the mid 1600's, Robert Boyle studied the relationship between the pressure **p** and the volume **V** of a confined gas held at a constant temperature. Boyle observed that the product of the pressure and volume are observed to be nearly constant. The product of pressure and volume is exactly a constant for an **ideal gas**.


 * //p * V = constant//**

This relationship between pressure and volume is called **Boyle's Law** in his honor. Here is a computer animation of this process:
