Physical Science Chapter 1 Lesson 1 What is Matter?
Liquid
has a certain volume but it has no shape of its own. A liquid takes the shape of its container. Milk and water are liquids
Gases
A gas, like liquids, does not have a shape of its own. Unlike a liquid, a gas does not have a volume of its own. When bubbles break, the gases spread out and take up more space.
How is a solution different from other mixtures?
A solution is a mixture which one substance spreads evenly throughout another substance. (Salt and water mixed together). A mixture is two or more substances mixed together but can easily separated.
Matter
All living and nonliving things are made of matter
Thick and thin pretzels
Both are made up of matter. Both have mass and take up space. One is thicker than the other. The thin pretzel has less volume
Mixtures
Can have different kinds and amounts of substances. A salad can have different amounts of each vegetable or different kinds of vegetables
What are two physical properties of matter?
Color, shape, size and mass
Solid
Has a shape and a volume of its own. Your desk and books are solids
How are mass and volume of an object different?
Mass is the amount of material that an object has in it. Volume is the amount of space that matter takes up. Both a thin and thick pretzel have mass, but the thin pretzel takes up less space than the thick pretzel.
State or form that matter has
One important property of matter is the state or form matter has. Matter has three states: solid, liquid and gas.
Mixtures
One kind of mixture forms when you mix salt and water together. the salt dissolves in the water. When it dissolves, the salt breaks into tiny bits that are too small to see. These bits spread out evenly throughout the water.
Solution
a mixture in which one substance spreads evenly throughout another substance
Matter
anything that has mass and takes up space
Property
something about matter that can be observed and tells you what the matter is like. Color, shape, size and mass are some physical properties of matter. These properties can be used to describe or sort mater
Another property of matter
the ability of some matter to float in a gas or liquid. An onion can float and a potato can not
mass
the amount of material that an object has in it
Volume
the amount of space that matter takes up
Mixture
two or more substances that are mixed together but can easily be separated
