Question

The gas in the piston is at constant temperature. A student increases the pressure on the piston from 2 atm to 3 atm. The observation will be summarized in a row of the incomplete table below.

Row Name Observation Constants
1 Boyle's law ? ?
2 Charles’s law ? ?
3 Gay-Lussac’s law ? Volume, moles of gas
4 Combined gas law ? ?

Which row of the table and which observation would the student fill?
a.row 1, volume decreases when temperature decreases
b.row 1, volume decreases when pressure increases
c.row 3, volume decreases when temperature decreases
d.row 3, volume decreases when pressure increases

Answer 1

B) row 1, volume decreases when pressure increases

Step-by-step explanation:

Answer 2

To increase the pressure inside the container at constant temperature, the student will have to push down the gas piston. This will result in a decrease in the volume occupied by the gas molecules. This observation is also stated by Boyle's Law wherein he states that at constant temperature, pressure and volume are inversely proportional to each other. Thus, the row of the table that should be filled with the corresponding observation is b.row 1, volume decreases when pressure increases.
