Changing States Today’s Goal:

Matter Definition  Anything that has mass and takes up space (has volume)  Matter is made up of atoms.

Phases and Phase Changes. The Phases Solid Liquid Gas Plasma ColdestHottest.

Melting Solid  Liquid Energy is added, particles speed up (endothermic) Melting Point: Temp. at which a substance melts Freezing Liquid  Solid Energy.

In a physical change, matter shifts shape or state.

Section A change in matter from one form to another is known as phase change. There are four main kinds. A substance always loses or gains heat.

Matter Definition  Anything that has mass and takes up space (has volume)  Matter is made up of atoms.

PHASE CHANGES Each state of matter is called a PHASE

Study Pack #3

Today’s Goals… I can describe physical changes.

Observing Physical Changes… BeforeChangeAfter Cutting Paper Crumpling Paper Molding Playdough Boiling Water

Observing Physical Changes… What was the difference between the befores and afters? What types of things changed? So, what is a physical change?

Physical Changes A change in physical properties Change the form or appearance of the substance A new substance is NOT formed You can often reverse it

Examples of Physical Changes Cutting Change in shape Molding playdough Changes in state –Melting –Freezing –Evaporation –Condensation
