Question

If we blow the ballon in the jar by blowing air through the pipe B, what changes can be observed in the beaker?why?

Answer 1

Boyle's law is PV=constant

this is satisfied only when n,T,R are constants.

while blowing wind into a balloon, ‘n’ i.e., number of molecules is not constant..

So it is not a violation of Boyle's law..

Thank you

That depends. When the baloon belongs to someone whose agreement (on a such experiment) is not received it can be even the civil law violation. I am seriously.

And the thermodynamics of an ideal gas laws are formulated for some conditions which are pre-conditions. So they state something like:

if (condition_is_true)

then

the following statement is true

No, it is not a violation of Boyle’s Law. Boyle’s Law assumes constant mass. When you blow into a balloon, you are adding mass (air) into the system.

 Boyle's Law explicitly applies to an isothermal, closed system. The balloon in your example is not a closed system, because you're introducing matter from somewhere outside of it. Boyle's Law therefore does not apply.
