Gas law constants

Boyles, Charles and Gay Lussac's laws each relate to the formula

 `(P_1\ \ V_1)/T_1=(P_2\ \ V_2)/T_2`

But each one of them has a different constant

Boyle's law = `T` constant (temperature constant)

Charles' law = `P` constant (pressure constant)

Gay Lussac's = `V` constant (volume constant)

Use the following mnemonic to remember this

Boy, That Charles Picks Gay Videos!

(remember gay means happy)

Boy That Charles Picks Gay Videos mnemonic to help remember gas law constants

Boy, That Charles Picks Gay Videos!

translates to

           `B`   `T`
  Boyle `=` Temperature constant
  `C`   `P`
  Charles `=` Pressure constant
  `G`   `V`
  Gay Lussac `=` Volume constant
