Two rods, one of iron and the other of aluminium, are heated to the same temperature. Then,

Statement I: The root mean square speeds of the molecules of different ideal gases at the same temperature are the same. Statement II: The average translational kinetic energy of molecules of different ideal gas are same at the same temperature.

Three idential capacitors are combined differently. For the same voltage to each combination, the one that stores the greatest energy is

Two identical rods of same metal are first waleded in series and then in parallel are maintained at same temperature difference then the ratio of heats conducted in same time is .

Two identical solid spheres have the same temperature.One of the spheres is cut into two identical pieces.These two hemispheres are then separated. The intact sphere radiates an energy Q during a given time interval. During the same interval, the two hemispheres radiate a total energy Q'. What is the ratio Q' // Q ?
