Q8 of 31 Page 90

An inflated rubber balloon contains one mole of an ideal gas, has a pressure p, volume V and temperature T. If the temperature rises to 1.1 T, and the volume is increased to 1.05 V, the final pressure will be

By Ideal Gas equation,


where P, V and T are the pressure, volume and absolute temperature; n is the number of moles of gas; R is the ideal gas constant. Considering the two cases,


, as n and R are constant, where P1, V1, T1 and P2, V2, T2are the pressure, volume and absolute temperature of first and second case respectively.


Now, substituting the values




i.e. between between p and 1.1p.

1 mole of H2 gas is contained in a box of volume V = 1.00 m3 at T = 300K. The gas is heated to a temperature of T = 3000K and the gas gets converted to a gas of hydrogen atoms. The final pressure would be (considering all gases to be ideal)

A vessel of volume V contains a mixture of 1 mole of Hydrogen and 1 mole of Oxygen (both considered as ideal). Let f1 (v)dv, denote the fraction of molecules with speed between v and (v + dv) with f2 (v)dv, similarly for oxygen. Then
