A fixed volume of a gas occupies 760cm3 at 27°C and 70 cm of Hg. What will be its vol. at s.t.p.

उत्तर
P1 = 70 CM OF Hg
V1 = 760 cm3
T1 = 27°C
P2 = 76 cm of Hg
V2 = ?
T2 = 273 K
Using the gas equation, `("P"_1"V"_1)/"T"_1 = ("P"_2"V"_2)/"T"_2`
`= (70 xx 760)/300 = (76 xx "V"_2)/273`
∴ V2 = `(70xx760xx273)/(300xx76) = 637`cm3

What will be the minimum pressure required to compress 500 dm3 of air at 1 bar to 200 dm3 temperature remaining constant?
2 liters of gas is enclosed in a vessel at a pressure of 760 mmHg. If the temperature remains constant, calculate pressure when volume changes to 4 dm3.
It is found that on heating a gas its volume increases by 50% and its pressure decreases to 60% of its original value. If the original temperature was −15°C, find the temperature to which it was heated.
A certain mass of gas occupied 850 ml at a pressure of 760 mm of Hg. On increasing the pressure it was found that the volume of the gas was 75% of its initial value. Assuming constant temperature, find the final pressure of the gas?
At a given temperature the pressure of a gas reduces to 75% of its initial value and the volume increases by 40% of its initial value. Find this temperature if the initial temperature was -10°C.
According to Charles’s law, at constant pressure, the temperature is inversely proportional to volume.
