Question

. Without completing the calculations, determine what the new volume will be in the problem below. Also, explain how you were able to determine the new volume without completing the calculations. Pay special attention to how the pressure is changing. Fifty (50.) mL of helium gas is stored at a pressure of 300 kPa. The pressure is changed to 150 kPa. What is the new volume? *

Answer 1

Answer: 25 mL ;

Step-by-step explanation:

Note: Boyle's law: P1 * V1 = P1 * V2 ;

pressure decreased by half, or "divided by 2" / as such:

so volume would be divided by 2 ; as such: 50. mL /2 = 25 mL.

The answer is: 25 mL .
