All three gas laws can be combined into a single statement called the __,which describes how the volume of a gas is affected by changes in pressure, temperature, and amount. When the values of any three of the variables P, V, T, and n are known, the value of the fourth can be calculated using the __. The proportionality constant R in the equation is called the __ and has the same value for all gases.
- ideal gas law
- ideal gas law
- gas constant
