Question

According to Boyle's law, the product of:.pressure and volume is a constant. Hence,

• A. if volume of lungs is increased, then pressure decreases proportionately
• B. if volume of lungs is increased, then pressure also increases proportionately
• C. if volume of lungs is increased, then pressure decreases disproportionately
• D. if volume of lungs is increased, then pressure remains the same.

Answer 1

The correct option is A if volume of lungs is increased, then pressure decreases proportionately

According to Boyle's law, the product of pressure and volume is a constant. Hence, if the volume of the lungs is increased, then pressure decreases proportionately.

So, the correct answer is 'if volume of lungs is increased, then pressure decreases proportionately'.
