Answer:
A calorimeter is an apparatus for measuring the amount of heat involved in a chemical reaction or other process.
By start heating the water so,
1- the physical changes to the water will begin by going through different states of matter such as solid, liquid and gas vapor.
2- Water is a compound, not an element (H2o).
3- It will change according to the temperature change also:
a- At zero C° it is at a freezing temperature.
b- when it starts to be heated from 0C° to 100 c°, it starts to change from freezing to the liquid state.
c- At 100C° the water starts to change from liquid to vapor state until it disappears.
