1. A gas is confined in a cylinder with a movable piston at one end. When the volume of the
Sedaia [141]

Answer: 211 kPa

Explanation:

Given that,

Original pressure of gas (P1) = 125 kPa

Original volume of cylinder (V1) = 760 cm3

New pressure of gas (P2) = ?

New volume of cylinder (V2) = 450 cm3

Since pressure and volume are given while temperature is held constant, apply the formula for Boyle's law

P1V1= P2V2

125 kPa x 760 cm3= P2 x 450 cm3

95000 kPa•cm3 = 450 cm3•P2

Divide both sides by 450 cm3

95000 kPa•cm3/450 cm3 = 450 cm3•P2/450 cm3

211.1 kPa = P2

[Round the value of P2 to 3 significant numbers. Hence, P2 becomes 211 kPa]

Thus, the new pressure within the cylinder is 211 kPa
