What pressure must be applied to keep a gas at 750 torr and 300 k at a constant volume of 200 ml if the temperature is raised to 450 k?

The pressure must be applied at 450 K should be 1,125 torr.

Explanation:

At constant volume of 200 mL

Initial pressure exerted by the gas =

Initial temperature of the gas =

Final pressure exerted by the gas =

Final temperature of the gas =

Applying Gay Lussac Law:

The pressure must be applied at 450 K should be 1,125 torr.

on passing the small ampere of electric current through the tube made of ar and hg of cfl generates uv rays which excites the fluorescent and thus emits the high radiation by consumption of just 5- 12 w in comparison to incandescent light which requires more power such as around 40 - 55 w to lighten.

moreover the life span of fluorescent or cfl is around 8000 h whereas the life span of incandescent is around 1200 h

hence, the building installed with incandescent lights bears more electricity bill.
