Gay Lussac’s Law - Practice Questions & MCQ

Gay-Lussac’s Law (Pressure-Temperature Relationship): 
Scientist Joseph Gay-Lussac as a result of his experiments gave a general relation between the temperature and the pressure of a gas. He found that the pressure of a given mass of a gas at constant volume is directly proportional to the temperature. 
So, Gay-Lussac's Law or Pressure-Temperature Law can be stated as, At constant volume, the pressure of a fixed amount of a gas is directly proportional to the temperature.
The Law may be expressed mathematically as

The above relationship can also be obtained by combining Boyle's Law and Charles Law. For different conditions of pressure and temperature.

Physical Significance of Gay Lussac's Law : 
It is seen that the pressure of the inflated tyres of automobiles is constant but in summers on a hot sunny day when the temperature IS high, then the pressure inside the tyres increases, and they may burst. Similarly in winters, on a cold morning, when the temperature is low, then the pressure inside the tyres decreases considerably.
