. 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 .

D) Change in climate requires the results of the different instruments measuring the same factor compared.
E) Different areas have developed different instruments to measure climate change.
Answer:
More than one instrument is needed to measure change in the climate system because its complexity. The climate system involves the interaction of the atmosphere, land masses, and bodies of water.
