Question

A balloon with a volume of 1 L is filled with a gas that has a pressure of 4 Pa. What is the new pressure of the gas if the balloon is squeezed down to a volume of .6 L​

Answer 1

The new pressure of the gas if the balloon is squeezed down to a volume of .6 L​ is 6.66 Pa

Step-by-step explanation:

Given:

`V_(1)`=1L

`P_(1)`=4 Pa

`V_(2)`=0.6 L

To find:
`P_(2)`

According to Boyles law, pressure and volume are inversely proportional. This relationship can be found only when the temperature and amount of gas remain constant.

The expression is given as,
`\bold{P_(1) * V_(1)=P_(2) * V_(2)}`

Substituting the values in the equation,

Now,

4 × 1 =
`P_(2)`×0.6

`P_(2)`=4/0.6

= 6.66 Pa

The same expression can be used to find the change in volume when pressure is given or vice versa
