States of Matter
What is solid?
This names the type of property that describes the way an object looks or feels. You can MEASURE or use your 5 senses to observe this property. Examples - mass, color, smell, volume, density, etc.
What is physical property?
The law of conservation of matter/mass states that matter can never be _______ or _______, but that it can be _________.
What is created, destroyed, and changed?
This describes when two or more substances are combined and can be EASILY separated. You can still see all of the individual parts.
What is a mixture?
This is what happens to MOST objects when they are heated
What is expand?
This state of matter is an airlike substance that does not have a shape. It's atoms are VERY spread apart!
What is gas?
This is the type of property that describes the way an object behaves chemically. Examples include flammability, toxicity, radioactivity, etc.
What is chemical property?
How would the mass of bread change before or after baking?
What is the mass would stay the same?
This describes when two or more substances are combined that can NOT be easily separated. Most of the time, one substance is dissolved into another. You can not see the individual parts.
What is a solution?
What is contract?
This state of matter is a fluid-like substance that takes the shape of its container. The atoms in this state of matter are spread farther apart than the atoms of a solid.
What is gas?
This type of change can be reversed. It ONLY changes the object's appearance. Examples include cutting, folding, melting, evaporating, condensation, freezing, peeling, etc.
What is physical change?
How would the mass of a burger change if you ADD ketchup to it?
What is the mass would increase?
Mass only changes when something is ADDED or REMOVED.
Are the following examples mixtures or solutions?
Trail Mix, M&M's, fruit salad
What is mixtures?
What might happen to your tires in the winter time?
What is they might go flat or have low pressure?
(Objects contract when cooled)
The amount of gravitational force acting on an object (How much gravity is pushing down on you)
What is weight?
This type of change is not reversible. In this change, a new substance is formed. Examples include rusting, burning, baking, cooking, food rotting, etc.
What is chemical change?
What is 10 grams?
Are the following examples of mixtures or solutions?
Lemonade, Kool-Aid, Sweet Tea, Coffee
What is solution?
What might happen to a metal rod that is left outside on a hot summer day?
What is it will expand?
The amount of matter in an object (Definition 1)
The amount of space an object takes up (Definition 2)
What is Mass and Volume?
Are these examples of a physical or chemical change?
The melting wax of a candle
Baking a pizza
What is physical?
What is chemical?
If you burn a pile of wood, how does the mass of the wood change, and where does the mass go?
What is the mass would not change, and the mass is turned into ashes, smoke, and gases.
How would you get the individual parts of solution back? For example, if you mix sugar into water until it dissolves, how could you get the sugar back?
What is you could let the water evaporate until only the sugar is left?
What happens to water when it is heated and cooled?
What is water contracts when heated and expands when cooled?
(Think back to the video of the lady measuring water level before and after freezing the water)
