Question

the pressure of a gas is doubled and the temperature is raised to 273K.what is the final volume?​

Answer 1

Answer:

Suppose the volume at STP to be V and pressure to be P and temperature to be T

Now, the number of moles of the gas X present

n=

RT

PV

PV=nRT

Now, the second condition

P

2

=2P

T

2

=3T

Now, the volume

V

2

=

P

2

nRT

2

Now, substituting the value of T

2

and P

2

V

2

=

P

2

nRT

2

V

2

=

T

PV

×

2P

3T

V

2

=

2

3

V

V

2

=1.5V

So, the final volume will be 1.5 fold the original volume.
