Question

half liter of air under 360mm pressure is compressed to 200ml.Taking the temperature to remain constant.find the new pressure​

Answer 1

Answer:

Ideal gas equation is given by

pV=nRT          ...(i)

For oxygen, p=1atm,V=1L,n=n0

Therefore equation (i) becomes

∴1×1=no2RT

⇒no2=RT1

For nitrogen p=0.5atm,V=2L,n=nN

∴0.5×2=nN2RT

⇒nN2=RT1

For mixture of gas

pmixVmix=nmixRT

Here, nmix=nO+nN2

∴RTpmixVmix=RT1+RT1

⇒p
