Report | Pranav chaudhary asks : A gaseous mixture enclosed in a vessel consists of one g mole of gas A with gamma=(5/3) and some amount of gas B with gamma=(7/5) at a temperature T. The gases A and B do not react with each other and are assumed to be ideal. Find the number of g moles of the gas B if gamma for the gaseous mixture is (19/13). |
Report | Joydeep roy asks : here ar a few questions . 1) a monoatomic ideal gas ,initially at temp.T1 ,IS ENCLOSED IN A CYLINDER FITTED WITH A FRICTIONLESS piston. The gas is allowed to expand adiabatically to a temperature T2 by releasing the piston suddenly. If L1 and L2 are the lengths of the gas column before and after expansion respectively, then T1/T2 is given by (a) [L1/L2]^2/3 (b) [L1/L2] (c) [L2/L1] {^ Here means to the power of } (d) [L2/L1]^2/3 2)a thin brass sheet at 10degree C and a thin steel sheet at 20degree C have the same surface area.The common temperature at whch both would have the same area is (coeff of linear exp. for brass & steel are 19*10^-6 /deg C & 11*10^-6/deg C RESP.) a)-3.75 degC (B)-2.75 degC (C) 2.75 degC (D) 3.75 degC SIR PLS SOLVE THESE QUESTIONS WITH SOME TIPS AND TRICKS ANS: (1)d (2)a |

Report | Rahul prajapati asks : thank you for your answer. But Sir,how bursting of tyre is adiabatic process?, please explain. sir i think that bursting of tyre is isochoric process as tyre tube has constant volume & in summer season tyre tube expands as temperature increases (since at constant volume pressure is directly propotional to temperature )due to more expansion tyre tube can't tolerate this pressure & burst out . Is i am wright sir? if it is wrong, then what is correct explanation for it. |
