Answer:
These two objects have different physical properties. For example, while at ambient temperature a piece of metal is solid, a mass of water is in a liquid state.
If you give heat to these two things, the water may suffer a process called vaporization, which is the process where a liquid transforms into a gas ( this happens at 100° C)
While in the case of the metal, may suffer a process called fusion, which is the process where a solid transforms into a liquid (and in this case you will have liquid metal) The temperature where this happens depends of the type of metal, for example for the led the fusion temperature is 340°C.
