A metal sphere is found to have a density (mass/volume) of 5.2 g/cm3 at 25C and a density of 5.1 g/cm3 at 50C?
Physics question: A metal sphere is found to have a density (mass/volume) of 5.2 g/cm3 at 25C and a density of 5.1 g/cm3 at 50C. Propose a hypothesis to explain this observation. How could one easily test this hypothesis?
Will be quick to award BA, thanks in advance for any help

when we increase the temperature of the metal sphere the internal kinetic energy of the atoms increasing, forcing them to take more space and increasing the volume of the sphere; hence for the same mass as the volume has increased, the density has decreased.
to easily test, heat and observe the volume change by amount of liquid displaced by it like immersing it in water.
and if you say this is 'hypothesis' i dont think you can verify it
