Question

A sample of gas under a pressure of 622 kPa has a volume of 233 cm3. The pressure is increased to 988 kPa, while the temperature remains constant. What volume will the gas occupy at this pressure?

Answer 1

\(\Large\sf P_1V_1=P_2V_2\)

\(\large\sf P_1=622~kPa\)
\(\large\sf V_1=233~cm^3\)
\(\large\sf P_2=988~kPa\)

Divide both sides by \(\sf P_2:\)
\(\large\sf V_2=\dfrac{P_1V_1}{P_2}\)
