Question

2500 cm3 of hydrogen is taken at S.T.P. The pressure of this gas is further increased by two and a half times (temperature remaining constant). What volume will hydrogen occupy now

Answer 1

Hello friend!!
Rajdeep here...

P1 = x, P2 = 5x/2
T1 = y, T2 = y [constant]
V1 = 2500, V2 = ?

By gas equation,
P1V1/T1 = P2V2/T2
=> 2500x/y = 5x × V2/2 × y
=> 2500 = 5V2/2 [x and y on both sides are cancelled]
So V2 = 2500x2/5
= 500x2
= 1000cm³

Hope this helps..
Thanks???

Mention not....

Answer 2

Answer:

V1=2500cm3

P1=1atm

P2=1+2 1/2

=1+3/2

=5/2

P1V1=P2V2

P1V1 =V2

P2

1×2500 =V2

5/2

1×500×2= V2

1000 cm3 =V2
