Characteristics of Matter
What is the definition of matter?
Matter is everything that has mass and occupies volume.
Name the three states of matter.
Solids, liquids, and gases.
Give an example of a change of state you might observe at home.
Boiling water to create steam.
Define physical changes in matter.
Physical changes are changes in the state, volume, or form of matter that do not result in the formation of a different substance.
Define chemical changes in matter.
Chemical changes are changes that result in the formation of different substances. Signs of chemical changes include color changes, gas production, or the formation of a precipitate.
What are the two properties that all matter has?
Mass and volume.
Oobleck was an example of which state(s) of Matter?
Solid and Liquid
What happens when water freezes?
Water changes from a liquid state to a solid state and the particles move closer together.
Give an example of a physical change.
Ex. Melting an ice cube.
Name one sign that a chemical change has occurred.
Can you always see matter? Why or why not?
No, matter is not always visible because it can be in the form of gases or tiny particles.
Describe the characteristics of solids. (Hint think about the shape and volume)
Solids have a definite shape and volume.
Explain the process of condensation.
Condensation is when a gas changes into a liquid state.
What happens to the volume of a liquid when it is poured into a different container?
The volume of the liquid stays the same.
Give an example of a chemical change we observed in class
Elephant Toothpaste
Define the characteristics of Gas
Gasses have no definite shape or volume, they can be compressed and expanded easily, and their particles are far apart and move freely.
Explain the process of Sublimation and provide an example of it.
Sublimation is the change of a solid directly to a gas, without passing through the liquid stage. An example of sublimation is dry ice at ordinary atmospheric pressure.
Explain the physical change that occurs when an ice cube melts.
When an ice cube melts, it undergoes a physical change from a solid state to a liquid state
Give an example of a chemical change that occurs during baking.
Baking a cake, where the ingredients undergo a chemical reaction to produce a cake with a different texture and flavor.
Define the characteristics of liquids.
Liquids have a definite volume but no definite shape; they take the shape of their container.
Explain the process of Deposition and provide an example of it.
Deposition is when a substance in a gas changes to a solid without passing through the liquid stage. An example is frost when water vapour in the air changes directly into ice when it comes in contact with a cold surface.
Give an example of a physical change that involves a change in shape.
Give an example of a chemical change that produces a gas.
The reaction between baking soda (sodium bicarbonate) and vinegar (acetic acid) produces carbon dioxide gas, which is observed as bubbles.
