Important States of Matter Formulas For JEE Main and Advanced

Find a list of formulas for the topic states of matter which candidates can go through and revise them before the entrance exams. The formulas are important and are often asked in JEE Main or Advanced.

State of Matter Formulas

1. Boyle’s Law:

P1V1 = P2V2 (at constant T and n)


2. Charles’ Law:

V1T1=V2T2(atconstantPandn)\frac{V_{1}}{T_{1}} = \frac{V_{2}}{T_{2}} (at\: constant\: P\: and\: n)


3. Avogadro’s Law:

V = kn (at constant P and T)

4. Ideal Gas Equation:

PV = nRT

M=dRTPM = \frac{dRT}{P}


5. Combined Gas Equation:

P1V1T1=P2V2T2:(n,Rconstant)\frac{P_{1}V_{1}}{T_{1}} = \frac{P_{2}V_{2}}{T_{2}} :(n, R\: constant)


6. Dalton’s Law of Partial Pressures:

PTotal = P1 + P2 + P3 + …Pn


7. Partial Pressure in Terms of Mole Fraction:

Pi = xi PTotal


8. Van Der Waals Equation:

(P+an2V2)(Vnb)=nRT\left ( P + \frac{an^{2}}{V^{2}} \right )(V – nb) = nRT


9. Compressibility Factor Z =

Z=PVRT(for1moleofgas)Z = \frac{PV}{RT} (for\: 1\: mole\: of\: gas)
