Question

An enclosed gas is at a pressure of 143,95kpa .if the volume is increased by 40% at constant temperature. what is the new pressure in kilopascals ?
​

Answer 1

All processes for which the temperature stays constant are described by Boyle's law.

Boyle's law is expressed as p1 * V1 = p2 * V2, where p1 and V1 are starting pressure and volume, respectively. The ultimate values of these gas parameters are p2 and V2.

Boyle's law formula can be stated in a variety of ways, depending on the parameter we want to estimate. Let's imagine we wish to determine the pressure that results from changing a gas' volume under isothermal conditions. The Boyle's law equation thus reads: p2 = p1 * V1 / V2 or p2 / p1 = V1 / V2.

As we can see, the final-to-initial pressure ratio is the opposite of the volume ratio.
