Question

3. A cylinder of 20 litres capacity contains a gas at 100
atmospheric pressure. How many flasks of 200 cm
capacity can be filled from it at 1 atmosphere pressure,
mana remaining constant? ​

Answer 1

Answer:

There will be no remaining constant.

Explanation:

200 litres contain= 100 atm

So,

1 litre will contain= 100/20

= 5 atm

1 litre=5 atm

but, 1 atm= ___ litres

For this,

5 atm= 1 litre

1 atm= 1/5

=0.2 litre

200cm= 0.2 litres

0.2 litre= 1atm (from above)

so 200cm (or 0.2 litres) flask can be filled from 1 atmospheric pressure.

Answer 2

Answer:

10,000 flask can be filled at 1 atm

Explanation:

Using the relation

-> (P1) x (V1) = (P2) x (V2)

-> (100 atm) x (20 litre) = (1 atm) x (V2)

Keeping in mind, 1 meter cube = 1000 litre

We get,

V2= 2000 litres

The above volume indicate that, we will have 2000 litre of gas available to be filled at 1 atm.

Now, assuming (since there is error in question as it does not mention the volumetric unit correctly) volume of each flask to be 200 cm cube.

We get,

-> 200 cm cube = 1 flask

( 1 litre = 10^3 cm cube)

-> 2000 X 10^3 cm cube = 10,000 flask
