Four Dials, One Equation

You'll learnto solve PV = nRT for one gas variable while the other three are held or known.

A cylinder of gas has four dials: how hard it pushes, how much room it takes, how much of it there is, and how hot it is. Turn one and the others have to answer. Twelve short steps; press Next for each one.

12 STEPS · 6 QUICK CHECKS · PV = nRT · R = 0.08206 L·atm·mol−1·K−1 · v4

four dials · one equation · and one rule that never bends
