Aballoon 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

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

Explanation:

Given:

=1L  

=4 Pa  

=0.6 L  

To find:

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,

Substituting the values in the equation,

Now,

4 × 1 = ×0.6

=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

answer: the exterior temperature of commercial jet planes as they leave the stratosphere and return to the ground increases steadily.

explanation:

the lower most layer of atmosphere is troposphere which extends from 0 to 12 km above the surface of the earth. the temperature initially decreases as distance is increased from the earth's surface. commercial jets fly in lower part of the stratosphere. the stratosphere extends upto 50 km. the temperature in stratosphere starts rising again due to presence of ozone which traps the uv rays.

thus, when the planes leave the stratosphere and return to the ground, the exterior temperature increases steadily.
