There are 500 molecules in an airtight bucket, and the volume is held constant. Which change would cause the greatest increase in pressure? (1 point)

A. adding 100 more molecules and increasing the temperature by 10K

B. adding 100 more molecules and decreasing the temperature by 10K

C. releasing 100 molecules and decreasing the temperature by 10K

D. releasing 100 molecules and increasing the temperature by 10K

The change that would cause the greatest increase in pressure inside an airtight bucket with 500 molecules would be the addition of 100 more molecules and increasing the temperature by 10 K.

According to gas laws:

at constant temperatures, pressure will always increase with an increase in volume because molecules will collide more frequently,
at constant volume, pressure will also increase with an increase in temperature because the kinetic energy of each molecule will increase, resulting in more collision among molecules.

Thus, all other things being constant, increasing either volume or temperature will lead to an increase in the pressure of the molecules in the airtight bucket.

Therefore, increase the volume by adding 100 more molecules and also increasing the temperature by 10 K will cause the greatest increase in pressure.
