Answer 1

yes.a reaction does take place.

Explanation:

an endothermic reaction takes place (intake of heat)

Answer 2

Answer:

  chemical reaction has taken place during this change.

Explanation:

We know that water is a compound that is made up of two elements hydrogen and oxygen and its formula is h2o . So when it is heated, the liquid turns into its gaseous form by the process of evaporation in which only its physical nature gets changed. Steam does not have any chemical formula because it is reversible on cooling and nothing but only the gaseous form of water. It is a chemical reaction in which heat is absorbed (endothermic change)
