. 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: 25 mL ;
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 .

Answer:
B) William Penn's careful planning and his policy of selling land to the settlers
Explanation:
William Penn was the founder, owner and governor of the Pennsylvania Colony. He received a British crown grant to establish a colony as payment for a debt that the royal family owed to his father.
Upon arriving in America, Penn had a very well done and meticulous plan to venerate land to the settlers who were interested. For this, he knew that Pennsilvania could not present conflict with the natives and for that reason he started a series of purchases from the territories of the Delaware Indians, who received a payment in exchange for the territory. Once free from the natives, he started selling land and it was a very promising and successful business.
