(chatquestion)...8. 1 gas A barometer tube, containing mercury, is lowered in a vessel containing mercury until only 50 cm of the tube is above the level of mercury in the vessel. If the atmospheric pressure is 75 cm of mercury, what is the pressure at the top of the tube? (a) 33.3 kPa (b) 66.7 kPa (c) 3.33 MPa (c) 9. 6.67 MPa One mole of a gas expands obeying the relation as shown in the P/V diagram. The maximum temperature in this process is equal to (Vo.Po) (2Vo.Po/2) Po Vo (a) ЗРО Vo (b) 9P,Vo (c) (d) None of these R. 8R A vessel with open mouth contains air at 60°C. When the vessel is heated upto temperature T, one fourth of the air goes out. The value of T is 10. (a) 80°C (b) 171°C (c) 333°C (d) 444°C of N2 gas is contained in a flask at a pressure of 10 atm and at a temperature of 57°. It is 11. 28 gm found that due to leakage in the flask, the pressure is reduced to half and the temperature reduced to 27°C. The quantity of N, gas that leaked out is 11/20 gm (b) 20/11 gm (c) 5/63 gm (d) 63/5 gm (a) vessel at...(9th)
