Question

water is filled upto same height in two identical closed containers A and B.Container A has vaccum over the water while container B has air over the water.At the same depth of both the containers there is an opening on which identical balloons A and B are attached.then
1 balloon A will bulge more than B
2 balloon B will bulge more than A
3 Both the balloons will bulge equally
4 none of the balloons will bulge

Answer 1

Consider two containers A and B containing identical gases at the same pressure, volume and temperature. The gas in container A is compressed to half of its original volume isothermally while the gas in container B is compressed to half of its original volume adiabatically. The ratio of final pressure of gas in B to that of gas in A is

2γγ-1

(1/2) γγ-1

(1/(1 -γγ )2

(1/(γγ- 1))2
