Draw molecules that forms when the h2o was in hot water

( h2 o2, h2o, -oh, o2)

and draw when molecules that form when h2o is in cold water
(H2 O2)

Hot water: high temperature
High velocity
(Long arrows) bonds break

Cold water: low temperature
Low velocity
(Short arrows)

Also make a key on what is used in both cold water and hot


Q&A: how does your model align with your observation?


Also draw water tank
