Question

Give reasons and state the type of change. A student removes a loaf of bread hot from the oven. The student cuts a slice off the loaf and spread butter on it.

Answer 1

Removing a hot loaf of bread from the oven and cutting a slice of bread and spreading butter on it are physical changes. They do not create new substances but alter the shape and form of the existing materials.

Step-by-step explanation:

This question involves two types of changes: physical and chemical.

Firstly, removing the loaf of bread from the oven involves a physical change; the bread becomes hot but does not alter its fundamental structure or composition.

Secondly, cutting a slice of bread and spreading butter also involves a physical change.

No new substances are created when these actions are performed. They are physical changes as only the shape and form of the bread and butter are altered.
