What is Matter? Properties of Matter
Matter is… everything that has mass and volume made up of atoms (tiny particles)
Mass and Volume
Mass is the amount of matter (or material) something contains. Mass can be measured using a balance scale. The unit for mass is the gram (g). Try a short investigation with mass.
Mass and Volume contd Volume is (1) the amount of space matter takes up and (2) the amount of matter something can contain. Volume can be measured (1) using a graduated cylinder or (2) by calculating the length x width x height. The unit for volume is the liter (L), milliliter (mL), or the cubic centimeter (cm 3 ). Try a short investigation with volume.
Particles – The 1 st Theory Atomic Theory of Matter (John Dalton) 1. elements are made up of tiny particles called atoms 2. atoms of the same element are identical; atoms of different elements are different 3. atoms are not created or destroyed 4. atoms can combine to form compounds
Particles – contd atoms made up of protons, electrons, and neutrons protons and neutrons make up the nucleus the number of protons determines the element electrons orbit the nucleus
Particles – contd
Physical Properties characteristics that are observed with the senses: physical state (solid, liquid or gas) color odor density melting point boiling point freezing point hardness
Physical Changes changes in physical properties like… cutting a piece of paper ice melting boiling water coloring a piece of paper placing food coloring in water
Physical Changes Changes in State
Kinetic Particle Theory of Matter matter made up of particles particles are in motion there is space between the particles changes in heat result in changes in particle motion changes in heat result in changes in space between particles
3 Common States of Matter also 3 common states of water solid, liquid, & gas also BE-condensate & plasma
Solid packed together but vibrate definite shape definite volume usually dense
Liquid fairly close together able to move in all directions no definite shape fill the bottom of a container definite volume
Gas fairly close together able to move in all directions and collide no definite shape expand to fill any container no definite volume usually low density
How does energy affect changes in state? HEAT IS ENERGY!
Kinetic Particle Lab To observe the affects of heat on the particles of matter. Materials: 3 containers water (cold, room temperature, & hot) food coloring timer
Lab Questions When you placed dye into the container filled with _?_ water, what did you observe? How long did it take for the dye to completely mix into the _?_ water? In which container did the water mix the fastest? Using the kinetic particle theory, explain what you observed.
Chemical Properties characteristics that describe how matter changes or interacts with other kinds of matter: paper burns iron rusts gold does not rust wood rots sodium reacts with water
Chemical Changes changes in chemical properties like… always changes in the form of matter matter is transformed completely into different materials
Chemical Changes contd iron turning into rust in moist air digesting food burning metals in fireworks
