Question

at a pressure of 152 CM HG a gas X has a volume of 50 cc at what pressure will the volume be 30cc temperature remaining constant throughout.​

Answer 1

$\boxed{BOYLE'S\:\: LAW :}$

In 1662, Robert Boyle founded the pressure - volume relationship of a dry gas at constant temperature.

Boyle states that, at constant temperature, the volume of a fixed mass of a dry gas is inversely proportional to its pressure.

$\boxed{Mathematical\:\:Expression :}$

P1V1 = P2V2 = K (At const. temperature)

The value of "k" however depends on the mass of dry gas and temperature of the gas.

$\bold{\huge{SOLUTION \: :}}$

____________________________________

✔ P1 = 152 cm Hg

✔ V1 = 50 cc

✔ P2 = ? cm Hg

✔ V2 = 30 cc

By Boyle's law,

P1V1 = P2V2

Or, (152×50) = (P2×30)

Or, P2 = 253.33 cm Hg [APPROX.]

Answer 2

Answer:

253.33 cm of Hg(Mercury)
