44.A container of 5 liter has a gas at pressure of 0.8 mcolumn of Hg. This is joined to an evacuated con-tainer of 3 liter capacity. The resulting pressure will be:- (At constant temp.)(2) 0.5m(4)3/4 m(3)2.0 m |

Answer» Since the temperature is constant, we must use Boyle's Law in this numerical. Let us identify the information we have :V1 = 5 litresP1 = 0.8 m of HgV2 = V1 + 3 litresV2 = 5 litres + 3 litresV2 = 8 litresTo find : P2Boyle's law gives the relation between the pressure and volume of a neutral and dry gas which is as follows : V1 * P1 = V2 * P2Substituting the values we know,5 * 0.8 = 8 * P2=> 4 = 8 * P2=> P2 = 4 / 8=> P2 = 0.5 m of Hg what is the meaning of * this sign..? |
