Asample of xenon gas occupies a volume of 5.82 l 5.82 l at 475 k. 475 k. if the pressure remains constant, at what temperature will this same xenon gas sample have a volume of 2.64 l?

215.5K

Explanation:

Charles' law states that, at constant pressure the volume of a given mass of gas is directly proportional to its temperature in Kelvin ( or absolute temperature ).

This means that for an increase in gas volume there is a corresponding increase in the Kelvin temperature and a decrease in gas volume will also result in a decrease in the Kelvin temperature.

During calculations, the temperature must be converted to Kelvin temperature if otherwise given.

Mathematically, V × T ( at constant pressure )

Introducing a constant,

V = KT where V= volume in litres, T= temperature in Kelvin, K= mathematical constant.

Also, for initial and final states of the gas,

V1/T1=V2/T2 where V1= volume at temperature T1 and V2= volume at temperature T2.

Using V1/T1=V2/T2 where V1= 5.82L, V2=2.64L, T1= 475K, T2= ?

T2=V2T1/V1 = 2.64 x 475/5.82 = 1254/5.82 = 215.5K

in chemistry, adhesion and cohesion are attractive forces that exist between molecules. they hold the molecules together from each other. they are different in that adhesive force exists between molecules of different substance while cohesive force happens between molecules of same substance.

adhesion between water and glass causes water molecules at the edge of water and glass interface to climb up the wall in a narrow glass tube. this is called capillary action. cohesion is what gives glass its shape and causes water to form a droplet.
