Do same amount of iron and copper at the same temperature hold same amount of heat ? Explain

The diameter of an iron sphere and the length of the side of an iron cube are equal. Initially they are at the same temperature. If they take the same amount of heat, whose final temperature will be higher?

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.

Two objects of iron and copper of same mass and same amount is given same heat, which object will became heated up quickly.

Statement I : A solid and a hollow sphere of same material when heated through the same temperature, will expand by the same amount. Statement II : The change in volume is independent of the original mass but depends on original volume.

A solid and a hollow cylinder of the same size and made of the same material are heated for the same change of temperature. Will the expansions be the same? Explain your answer.

Equal number of molecules of an ideal monatomic and an ideal diatomic gas are at the same temperature. Which gas will be more heated if equal amount of heat is supplied from outside?
