Tap to reveal answer
In the situation presented, Annie is correct. The changes to the bread are not able to be reversed once it has been heated up and turned into French toast. In some instances, these changes can be reversed like an ice cube or chocolate bar. If these items are melted, they can be cooled and will return to a solid. Once the bread is cooked, it cannot be changed back.

Sammie is correct in this situation. Once the fireworks are lit and the explosion happens, there is no way for this change to be reversed. The firework cannot be "unlit" and put back into the container once the heat has been applied. Something like a chocolate bar can have heat applied and then reversed once it is cooled, but fireworks are an example of something that cannot be changed.

The statement in the question is correct. Some changes can be reversed when something is heated or cooled, and others cannot. Boiling water can be reversed, once the steam cools it is liquid water again. Lighting a piece of paper on fire cannot be reversed; the paper cannot be returned to its original state.

The photo that demonstrates a change that cannot be reversed is the pan of brownies. Writing with markers can be erased and reversed, ice cubes can be heated and cooled multiple times between states, and a puzzle can be taken apart and put back together. Once the ingredients are mixed into a batter and then heated, the brownies cannot be turned into mixture again.

The photo is an example of a change that CAN be reversed. If the large block of ice starts to melt and the temperature drops again, it will refreeze. If the Sun comes out and it warms up, it will begin to melt again.

The photo that demonstrates a change that cannot be reversed is the plate of pancakes. Water that has been frozen into snow can be turned back to a liquid, and ice cream and popsicles can be refrozen if melted. Once the ingredients are mixed into a batter and then heated, the pancakes cannot be turned into mixture again.
