Question

Which does not describe a physical change happening to water?

water evaporating in the sun
water reacting with nitrogen gas
water freezing and being broken apart with a knife
water heating up on a stove

Answer 1

water reacting with nitrogen gas i think, since it doesn’t actually react

Answer 2

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.
