Matter Basics
Anything that has mass and takes up space.
What is Matter?
The ability of a material to be attached to a magnet.
What is magnetism?
A paper clip sticks to a magnet. Which property are you observing?
What is magnetism?
A change in size, shape, or state that does NOT create a new substance.
What is physical change?
True or false: Cutting a piece of paper creates a new substance.
False
The amount of matter in an object.
What is mass?
The ability of matter to dissolve in a liquid.
What is solubility?
Sugar disappears when stirred into water. Which property allows this?
What is solubility?
A change that produces one or more new substance.
What is chemical change?
A student melts a chocolate bar. Physical or chemical change?
Physical change
The amount of space an object takes up.
What is volume?
Thia describes how light bounces off an object.
What is reflectivity?
A metal spoon allows heat to travel through it.
What is conductivity?
Ice melting into water is this type of change.
What is a physical change?
A student burns a piece of paper and ash forms. Physical or chemical change?
Chemical change
A characteristic of matter that can be observed or measured without making a new substance.
What is a physical property?
This describes how easily heat or electricity can move through a material.
What is conductivity?
A shiny mirror bounces light back toward you.
What is reflectivity?
A nail rusting is this type of change.
What is a chemical change?
Which has more mass: an object with the mass of 25g or an object with the mass of 52g?
52g
A characteristic that can only be observed when matter changes into a different substance.
What is a chemical property?
Mass, volume, magnetism, and conductivity are all examples of this type of property.
What are physical properties?
You measure how much space a box takes up. What property are you measuring?
What is volume?
Matter is not created or destroyed during a physical or chemical change.
What is the conservation of mass?
A student mixes two substances and a completely new substance forms. What evidence tells you this was a chemical change?
A new substance was produced.
