The table below contains the values of pressure measured at different temperatures for 1 mole of an ideal gas. Plot the values in a graph and verify the Gay Lussac’s law. [Lines in the pressure vs temperature graph are known as iso chores (constant volume) of a gas]

Temperature (in deg celcius) 32 69 94 130 154 191
Pressure in 50 L container (atm) 0.51 0.56 0.6 0.66 0.7 0.76
Pressure in 75 L container (atm) 0.34 0.37 0.40 0.44 0.47 0.51

Gay Lussac’s law at constant volume = \(\frac{P_1}{T_1}\) = \(\frac{P_2}{T_2}\)

If temperature increases, pressure also increases. 

So \(\frac{P_1}{T_1}\) = \(\frac{P_2}{T_2}\)
