Question

If 500 mL expandable cylinder with a pressure of 500

Answer 1

Answer:

0.274 L

Explanation:

Applying Boyle's law,

PV = P'V'................. Equation 1

Where P = Initial pressure, V = Initial volume, P' = Final pressure, V' = Final volume.

make V' the subject of the equation,

V' = PV/P'............. Equation 2

From the question,

Given: P = 500 mm Hg, V = 500 mL = 0.5 L, P' = 1.2 atm = 912 mm Hg

Substitute these values into equation 2

V' = (0.5×500)/912

V' = 0.274 L

Hence the new volume is 0.274 L
