How can ice water and steam be three states of a substance and not different substances?

Well you can prove they are the same substance by experimenting. If you boil liquid water it turns into steam and if you then cool the steam, it turns back into liquid water. If you cool liquid water it will freeze and turn into ice and then if you warm the ice it will melt and tun back into liquid water. Thus the common substance in all three states is the water. ------------------------------------------------------------- In general substance are either solid, liquid or gaseous at normal temperatures and pressures and if you heat the solids they will turn into liquid then gas and if you cool the gases they will tun into liquid and then solids. Solid, liquid and gas are 3 of the possible states of matter (there are other states possible)


How do I prove that the varying temperature is an error in my lab report?

More Info: In a lab to prove that the temperature of matter can not change if it is going through a state change, data for the state change from solid to liquid has a small variation (the temp probe read melted water instead of the ice). How do I academically explain/ justify this in my lab write up?


How do you know that air exhaled by us contain watervapour?

We can perform a very simple activity to prove it practically. Hold a glass in front of your mouth on a cold day and exhale. You'll find that tiny liquid water droplets will be visible on the surface of the glass. The water vapour condenses due to the cool temperature of the environment. This easily proves the question
