उत्तर

The average K.E per molecule `bar"KE"` = ϵ = `3/2"kT"`

The equation implies that the temperature of a gas is a measure of the average translational K.E. per molecule of the gas.

Which of the following parameters is the same for molecules of all gases at a given temperature?


Find the number of molecules of an ideal gas in a volume of 1.000 cm3 at STP.


Figure shows two rigid vessels A and B, each of volume 200 cm3, containing an ideal gas (Cv = 12.5 J K−1 mol−1). The vessels are connected to a manometer tube containing mercury. The pressure in both the vessels is 75 cm of mercury and the temperature is 300 K. (a) Find the number of moles of the gas in each vessel. (b) 5.0 J of heat is supplied to the gas in vessel A and 10 J to the gas in vessel B. Assuming there's no appreciable transfer of heat from A to B, calculate the difference in the heights of mercury in the two sides of the manometer. Gas constant, R = 8.3 J K−1 mol−1.


Answer in brief:
