1.	Temperature at the foot of a mountain is 30^@C and pressure is 760mm whereas at the top of the mountain these are 0^@C and 710mm. Ratio of the densities of the air at the foot and the top of the mountain is ____(approx)
Answer» SOLUTION :`(d_1)/(d_2) = (P_1//T_1)/(P_2//T_2) = (760//303)/(710//273) ~~ 1`
