If steam escapes from a teapot is that chemical reaction explain please?
yes and no, it depends on what you would consider a chemical reaction. most people define a chemical reaction as when two or more chemicals react together, steam escaping from a pot, however, is not two chemicals, it is just water evaporating and condensing in the air to make steam which is hotter than air so it rises out of the pot, so it isn't a chemical reaction, so much as a 'change of chemical state'.
Is steam turning into water chemical or physical?
Chemical changes are those in which the chemical composition of a substance changes during the process. But when steam turns into water or vice versa, only the physical state of the substance undergoes a change but the chemical composition remains same. Thus steam turning into water is a physical change.

Why would the dissolution of table salt in water be considered gray area between chemical and physical change?
Because when the salt is dissolved, the chemical makeup of the crystal changes, making it a chemical change. However, you can evaporate the water, capture all the steam, cool the steam, and then you have the salt (original chemical makeup) and the water, making it a physical change.
