Answer:

Water reacting with nitrogen gas

Step-by-step explanation:

A physical change occurs when matter changes its form without a change in its chemical identity. A chemical change, on the other hand, occurs through a chemical reaction, forming new products.

When water evaporation, freezing, and heating produce physical changes in water, therefore the correct answer is "Water reacting with nitrogen gas" because it alludes to a chemical reaction.

I hope you find this information useful and interesting! Good luck!
