When zinc granules are reacted with dilute HCl (hydrochloric acid), zinc chloride i.e. ZnCl2 is formed along with the evolution of hydrogen gas H2.
The reactions between metals and acids are always endothermic.
When sulphuric acid is added to zinc granules , the gas produced is hydrogen gas. Zinc displaces hydrogen from sulphuric acid.
coz when we dilute zinc granules are reacted with dilute HCl (hydrochloric acid), zinc chloride i.e. ZnCl2 is formed along with the evolution of hydrogen gas H2. the presence of hydrogen gas can be tested by bringing a naked flame to the mouth of the test tube. Hydrogen gas burns with a pop sound.

They get converted to zinc sulfate

You'd only need dilute nitric acid reacting with zinc powder or granules
the test tube which holds the zinc becomes hot , the zinc turns into zinc chloride and hydrogen gas is produced. It is a chemical change.

The reaction between sulfuric acid and zinc produces zinc sufate and hydrogen gas
Yes, exothermic reaction: Zn + H2SO4 --> ZnSO4 + H2 Zinc + Sulfuric acid --> Zinc Sulfate + Hydrogen(gas)
It is a chemical reaction. 2HCl + Zn = ZnCl2 + H2
