Question

I need ur help...
give me solution

Answer 1

$\bold{Hello}$

As the values in the question is not readable , so i am taking normal values of the exponents .

This question can be easily solved by applying the equation of Boyle's law .

$\bold{P1V1 \:\: = \:\: P2V2}$

Here :-

P1 = 5 × 10^5
V1 = 0.25

P2 = 6 × 10^5
V2 = ?

We have to take out change in volume , that is = ( V2 - V1 )

we have to take out V2 .

Putting the values in equation , we get :

V2 = $\bold{\frac{5*10^{5}*0.25}{6*10^{5}}}$

By solving above equation , V2 = 0.208

So , V2 = 0.20. and. V1 = 0.25

Change in volume :-

=> 0.20 - 0.25

Change in volume = - 0.05

-ve sign shows that the volume has decreased.




*( Answer doesn't matter , Concepts should be strong . )
