Question

If a gas is compressed from 4L to 1L, and the temperatures remained constant, what happens to the pressure?

Answer 1

According to Gay lussac's law

$\\ \rm\Rrightarrow P\propto T$

• Pressure is directly proportional to temperature
• Temperature is constant so no use of this

But according to Boyles law

$\\ \rm\Rrightarrow P\propto \dfrac{1}{V}$

If volume is decreased by 4 times then pressure is increased by 4times
