Charle’s law

The Charle’s law is another important gas law, essential in the understanding the physics related to gases. The Charle’s law states that the volume of a gas at constant pressure is directly proportional to the temperature of the gas.

In other words with any increase in the volume of the gas the temperature will also increase if its pressure is maintained the same. Similarly, with any decrease in the volume of the gas while keeping its pressure constant will decrease the temperature of the gas.

This law is essential do understand the basic relationship between volume and temperature of a gas.

Furthermore we understand from this law that any change in temperature will result in a change in the volume of the gas with the pressure being the same. That is if a gas gets heated up, it will expand and when it gets cooled it diminishes in volume.

The Charle’s law has its own implications in the understanding and usage of the gases used in anesthesia. Better knowledge of this law explains us the changes taking place in the gas cylinders and the Boyle’s machine, which are necessarily used in anesthesia practice.

The other gas laws apart from Charle’s law that need to be known are the Boyle’s law and the Graham’s law.
