The Ideal Gas Law and Some Appliions - …

The ideal gas law is used like any other gas law, with attention paid to the units and making sure that temperature is expressed in kelvins. However, the ideal gas law does not require a change in the conditions of a gas sample.The ideal gas law implies that if you know any three of the physical properties of a gas, you can calculate the fourth property.
