If the temperature is kept constant, what change in volume would cause the pressure of an enclosed gas to be reduced to one-third of its original value? a) increasing the volume by a factor of nine b) decreasing the volume by a factor of three c) increasing the volume by a factor of three d) decreasing the volume by a factor of nine

c) increasing the volume by a factor of three.

Explanation:

Hello,

By recalling the Boyle's Law:

One states the pressure change:

Now, replacing the pressure at the second state one obtains for the volume at the second state:

Finally, one concludes that the volume must be increased by a factor of three.

Best regards.
