Given a container of helium gas with an initial volume of 39 L and temperature of 310K, calculate the new if the
temperature is changed to 31K

v2 = 3.9 L

Explanation:

no starving yourself won't it will make you lose more weight what you need to do is find out what foods make you gain weight like bread and meats with fat on

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.
