A gas cylinder having a capacity of 20 litres contains a gas at 100 atmos. How many flasks of 200 cm3 capacity can be filled from it at 1 atmos. pressure if the temperature remains constant?

उत्तर
V1 = 20 lits. = 20000 cc
V2 = ?
P1 = 100 atm
P2 = 1 atm
At constant temperature
P1V1 = P2V2
`"V"_2 = ("P"_1"V"_1)/"P"_2 = (100 xx 20000)/1 = 2000000` cc
∴ Number of flasks of capacity 200 cc
n × 200 = 2000000
n = `2000000/200 = 10000` flasks
