Help pls!! H2O(g) → H2O(l)

The chemical equation above describes a(n) .
A) irreversible state change
B) physical change
C) endothermic change
D) chemical change

C, physical change

Explanation:

take a look at the equation. Next to each form of water do you see the little (g) and (l)? These represent the state of matter the water is in. So, the water is going from a gas to a liquid. The chemical compound is the same so its a physical change, not chemical, and it is reversible. You could change the liquid water back to the gas through evaporation. Endothermic has literally nothing to do with this equation so you can easily eliminate that answer choice.

i think it's letter a.
