If measurements of gas are 75 l and 300 kilopascals and then the gas is measured is second time and found to be 50 l, describe what happened to the pressure if the temperature remains the same. include which law supports the observation

The pressure must have increased in the process

Explanation:

The State Equation for gasses reads:

where P is the gas' pressure, V its volume, n the number of moles of gas,  R the gas constant and T the temperature in degrees Kelvin.

If the temperature of the gas doesn't change in the described process, the right hand side of the equation stays the same. If that is the case, given that when the Volume of the gas diminishes from 75 liters to 50 liters, then the pressure must have increased to keep that product "P * V" constant:

So the pressure must have gone up to 450 kilopascals.

can you put the answers on the bottom so i can answer it
