Answer:
Can we calculate the temperature of both the things if 50J of energy is provided to an iron bar (of density 7.874 g/cm^3) and if the same energy was to be supplied to a cup of water (of density 0.997g/cm^3)
If yes, then please send a solution.
Note: Ignore that temperature can be lost via heat transfer from the water/iron to the body (of the container), to the atmosphere etc
