What are the variables of the Ideal Gas Law?
Answers
GPT-4o mini
The Ideal Gas Law is a mathematical relationship that describes the behavior of ideal gases. It can be expressed with the equation:
\[ PV = nRT \]
where:
- \( P \) = Pressure of the gas (usually in atmospheres, pascals, or mmHg)
- \( V \) = Volume of the gas (usually in liters or cubic meters)
- \( n \) = Number of moles of the gas (a measure of the amount of substance)
- \( R \) = Ideal gas constant (approximately 0.0821 L·atm/(K·mol) or 8.314 J/(K·mol), depending on the units used)
- \( T \) = Absolute temperature of the gas (in kelvins)
These variables interact in such a way that for an ideal gas, when any three of the variables are known, the fourth can be calculated.
