Question

The volume of a gas is reduced from 4 L to 0.5 L while the temperature is held constant. How does the gas pressure change?

It increases by a factor of two.
It increases by a factor of eight.
It decreases by a factor of eight.
It increases by a factor of four. ​

Answer 1

Answer:

It increases by a factor of eight

Explanation:

When temperature is held constant, gas pressure changes according the volume, in undirectly proportion.

Volume increases →  Pressure decreases

Volume decreases → Pressure increases

As volume gas, was reducted from 4L to 0.5L, it was reduced by 1/8, so the pressure gas was increased by a factor of eight.

Answer 2

Answer:

It increases by a factor of eight.
