Compare and contrast what happens in a metal to what happens to a mass of water when each is heated

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.

the temperature and the pressure affect solubility. temperature affects by changing the properties of the solvent. the increase in pressure increases solubility, the decrease in pressure decreases solubility.

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.
