Gay+Lussac

P1/T1=P2/T2

Gay-Lussac investigated the relationship between the Pressure of a gas and its temperature. Gay-Lussac's law, known as the law of combining volumes, states that the ratio between the combining volumes of gases and the product, if gaseous, can be expressed in small whole numbers. This law holds true because temperature is a measure of the average kinetic energy of a substance; as the kinetic energy of a gas increases, its particles collide with the container walls more rapidly, thereby exerting increased pressure.


 * PROBLEM:**The gaseous contents in an aerosol can are under a pressure of 3.00 atm at 25C. directions on the can caution the user to keeo the can in ap lace where the temperature does not exceed 52C. What would the presseure of the gas in the aerosol can be at 52C?

Given; P1=3 atm T1=25C + 273= 298K T2=52C + 273= 325K

UNKNOWN; P2

P2=P1T2/T1 P2=(3ATM)(325K)/298k=3.27 atm
