Matter and changes in matter Unit 5

Temporary deformation

• When a material returns to its previous shape after the force that caused the change has been removed.

• Reversible changes between solid, liquid and gas.

• When the material or substance can be returned to its previous state, and no new material or substance is produced.

• When substances interact and produce a new substance.

Change of state

• When a material returns to its previous shape after the force that caused the change has been removed.

• Reversible changes between solid, liquid and gas.

• When the material or subtance can be returned to its previous state, and no new material or substance is produced.s

• When substances interact and produce a new substance.

Reversible change

• When a material returns to its previous shape after the force that caused the change has been removed.

• Reversible changes between solid, liquid and gas.

• When the material or substance can be returned to its previous state, and no new material or substance is produced.

• When substances interact and produce a new substance.

Chemical change

• When a material returns to its previous shape after the force that caused the change has been removed.

• Reversible changes between solid, liquid and gas.

• When the material or substance can be returned to its previous state, and no new material or substance is produced.

• When substances interact and produce a new substance.

Combustion

• A change in the form or shape of a substance, but not in its composition

• A chemical change that produces heat and often light

• Changes that take place in the physical shape of material when force is applied.

• When material does not return to its previous shape after the force that caused the change in shape has been removed

Permanent deformation

• A change in the form or shape of a substance, but not in its composition

• A chemical change that produces heat and often light

• Changes that take place in the physical shape of material when force is applied.

• When material does not return to its previous shape after the force that caused the change in shape has been removed

Expansion

• The soft grey substance that is left behind when wood is burnt

• When oxygen combines with a substance and changes the substance´s composition, forming a new substance

• When the material or substance cannot be returned to its previous state, because its chemical composition or its structure are now different.

• When an object gets larger, for example when it is heated or subjected to an increase in pressure
