Find out the rms speed of a gas of density 2g.L^-1 at 76 cmHg pressure. Given density of mercury= 13.6 g.cm^-3 and g=980 cm.s^-2 .

The reading in a barometer changes from 75 cmHg to 25 cmHg when 10 cm^3 of air of atmospheric pressure is introduced in the vaccum space of the barometer tube. What is the volume of air in the tube?

The reading of a barometer decreases from 75 cmHg to 65 cmHg when some air is introduced in the vaccum space of the tube.Initial length of the space was 6 cm.IF the area of cross section of the tube is 1 cm^2 What is the volume of this air at standard pressure?

Work done during isothermal expension of one mole of an ideal gas from 10 atm to 1 atm at 300 K is

A and B cells are contiguous. Cell A has OP=10 atm, TP=7 atm and DPD=3 atm. Cell B has OP=8 atm. TP=3 atm and DPD=5 atm. The result would be
