Question

a balloon filled with water is placed in a microwave until it bursts. Name two different physical changes that occur during this reaction.

Answer 1

Explanation:

(1) water changes into steam

sorry but I don't know the other one

Answer 2

Answer:

• When a balloon filled with water is placed in a microwave until it bursts, the water in the balloon gets heated first, then due to prolonged heating it gets super-heated and the water gets converted to vapor which leads to steam explosion.
• This is because water expands on heating making the balloon also to inflate and with superheating, it will burst.
• So boiling of water, expansion of water due to superheating, and steam explosion are the physical changes that occur during the reaction.
