What does the ideal gas law allow a scientist to calculate that the other gas laws do not?

Answer 1

Natalie Anton

Quick answer: nothing.

There are four gas laws.

Boyle's Law

Volume is inversely proportional to pressure, or #PV = k#.

Charles' Law

Volume is directly proportional to temperature, or #V/T = k#

Gay-Lussac's or Amonton's Law

Pressure is directly proportional to temperature, or #P/T = k#

Avogadro's Law

Volume is directly proportional to the number of moles, or #V/n = k#

Put them all together, and you get

The Ideal Gas Law

#(PV)/(nT) = k# or #PV = nkT#

We usually replace the constant #k# with the universal gas constant #R# and write the equation as

#PV = nRT#

The Ideal Gas Law is simply a combination of the other four gas laws.

The ideal gas law allows a scientist to calculate the amount of gas using the equation PV = nRT, where P is pressure, V is volume, n is the number of moles, R is the gas constant, and T is temperature.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
