Answer 2

A physical change takes place in the shape of the toothpaste tube when we squeeze it.

• A physical change refers to the changes in shape and size of an object which can be reversed back to its original form.

• When we squeeze a toothpaste tube, we are using an external force to change the shape of the tube.

• This shape can also be brought back to its original form by the application of external force.

• It is not a chemical change because no change in the chemical composition of the tube is taking place.
