Why are the properties of mixtures and fluids and their uses important to us?

 Matter is anything has mass and takes up space (has volume) What is matter?

 Matter is anything has mass and takes up space (has volume)  There are three different states or phases of matter: What is matter?

 Matter is anything has mass and takes up space (has volume)  There are three different states or phases of matter:  Solid – definite shape and volume What is matter?

 Matter is anything has mass and takes up space (has volume)  There are three different states or phases of matter:  Solid – definite shape and volume  Liquid – no definite shape but definite volume What is matter?

 Matter is anything has mass and takes up space (has volume)  There are three different states or phases of matter:  Solid – definite shape and volume  Liquid – no definite shape but definite volume  Gas – no definite shape or volume What is matter?

 In order to understand further the properties of these phases, you need to get down to the particle level. The Particle Model of Matter

 The particle model has 3 key ideas: The Particle Model of Matter

 The particle model has 3 key ideas: 1)All substances are made up of tiny particles. The Particle Model of Matter

 The particle model has 3 key ideas: 1)All substances are made up of tiny particles. 2)The particles are always in motion. They will move faster as energy is added or slow down as energy is taken away. The Particle Model of Matter

 The particle model has 3 key ideas: 1)All substances are made up of tiny particles. 2)The particles are always in motion. They will move faster as energy is added or slow down as energy is taken away. 3)The particles are always colliding. The Particle Model of Matter

They will move faster as energy is added or slow down as energy is taken away. 3)The particles are always colliding.  Actually, there are 2 more key ideas but we’ll get to those later… The Particle Model of Matter

 Solids  Particles are tightly packed and moving with mainly a vibrational motion.  Very low energy. Applying the Particle Model to Phases of Matter

 Liquids  Particles are vibrating and rotating and so there are bigger spaces between them.  The particles don’t form rigid clumps which is why they take the shape of the container they are in. Applying the Particle Model to Phases of Matter

 Gases  Particles have very high energy and so have rotational, vibrational and translational movement.  There are large spaces between the particles. Applying the Particle Model to Phases of Matter

 As the particles gain or lose energy, they move closer or further apart.  This change in energy results in changes of state.  Fill in diagram… Changes of State

 As the particles gain or lose energy, they move closer or further apart.  This change in energy results in changes of state. Changes of State

 True and False  Get up and do simulations.  Fish  Relay Race  White boards practice Changes of State
