1.	4. A steel cylinder of internal volume 20 litres is filled withhydrogen at 29 atmospheric pressure. If hydrogen is usedto fill a balloon at 1-25 atmospheric pressure at the sametemperature, what volume will the gas occupy ?[Ans. 464 litres
Answer» Answer: According to BOYLE's law Explanation: P_1V_1= P_2V_2P 1 V 1 =P 2 V 2 if P_1 = 29 \ atm, V_1 = 20L, P_2= 1.25\ atmP 1 =29 atm,V 1 =20l,P 2 =1.25 atm, then V_2= \dfrac {29 \times 20}{1.25} = 464\ LV 2 = 1.25 29×20 =464 L

Answer:

According to BOYLE's law

Explanation:

P_1V_1= P_2V_2P

if P_1 = 29 \ atm, V_1 = 20L, P_2= 1.25\ atmP

=29 atm,V

=20l,P

=1.25 atm, then V_2= \dfrac {29 \times 20}{1.25} = 464\ LV

1.25

29×20

=464 L
