What will be the temperature in degree celsius if TF=96F?
A capillary tube of radius 0.4 mm is dipped vertically in water. Find up to what height the water will rise in capillary. If the capillary is inclined at an angle of of 60 degree with the vertical, how much length of the capillary is occupied by water? Surface tension of water is 7.0×10 to the power −2N per meter.
An open flask containing air is heated from 300K to 500K. What percentage of air will be escaped to the atmosphere, if the pressure is kept constant ?
The molecular weight of a gas which diffuses through a porous plug at 1/6th of the speed of hydrogen under identical condition is:
1 mole of each of X1,X2,X3 with van der Waal's constants a (in atm L3mol−2) 1.0, 3.8, 2.1 respectively is kept separately in three different vessels of equal volume at identical temperature. Their pressures are observed to P1,P2, and P3 respectively. On the basis of this data alone, select the correct option (neglect the effect of 'b') :
Two vessels connected by a valve of negligible volume. One container (I) has 2.8 g of N2 at temperature T1(K). The other container (II) is completely evacuated. The container (I) is heated to T2(K)while container (II) is maintained at T2/3(K). volume of vessel (I) is half that of vessel (II). If the valve is opened then what is the mass ratio of N2 is both vessel (WI/WII)?
