Step 6: Measure Pressure and Volume with the Book and 1 kg of Weight
Total the mass on the syringe. Record it in the
correct row of the data table
kg
DOWE
Click and drag weights to change the pressure,
Click the syringe to zoom in and see the volume,

what is the volume occupied by 40 grams of argon gas (ar) at standard conditions? what volume, in liters, is occupied by 1.5 x 1023 

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.
