Q. Statement 1: A hollow metal sphere floats on water at , then if the temperature is increased, the force of buoyancy increases.

Statement 2: On increasing the temperature the volume of the hollow sphere will increase.

Solution:

Statement-1 is false, Statement-2 is true. Since the hollow metal sphere floats, its weight is supported by buoyant force. As weight does not change on increasing the temperature, the buoyant force does not change.
