Two sphere of same radius and material, one solid and one hollow are heated to same temperature and kept in a chamber maintained at lower temperature at t = 0 -

Two spheres of the same radii, one solid and other hollow are charged to the same potential, which one has greater charge?

Two metallic spheres A and B are made up of same material and also have identical surfaces. Both spheres are heated to same temperature and are then placed in a chamber which is at a lower temperature, thermally insulated from each other. If ratio of masses of A and B is 3:1, then the ratio of their initial rate of cooling is

Two spheres of same material and radius r and 2r are heated to same temperature and are kept in identical surroundings, ratio of their rate of loss of heat is

Two spheres of same material and radius r and 2r are heated to same temperature and are kept in identical surroundings, ratio of their rate of loss of heat is

Two spheres of same size are made of same metal, but one is hollow and the other is solid. They are heated to same temperature then

Two spheres of same size are made of same metal but one is hollow and the other is solid.They are heated to same temperature,then

A solid sphere and a hollow sphere are heated the same temperature . Point out the true statement.
