Mrs. Buchanan - Physical and Chemical Properties and Changes

QuestionAnswer
Boiling water is a physical change
the temperature at which water boils is a physical property
the ability of a metal to be pressed into sheets is a physical property
At room temperature, water is a liquid physical property
Is magnetism a size dependent or size independent physical property size independent
what are the three size dependent physical properties of matter weight, mass, volume
why is density a size independent physical property? it's based on a ratio. As mass increases, so does volume.
Petroleum is a flammable substance chemical property
lead can be toxic if ingetsted chemical property
solid changes to liquid melting
solid changes to gas sublimation
liquid changes to solid freezing
liquid changes to gas vaporization
gas changes to liquid condensation
gas changes to solid deposition
A change in the state of matter is a _______________ change physical
A change in energy indicates which kind of change chemical
If a gas or solid is produced when you mix two substances, it is most likely a chemical change
a solid that forms during a chemical reaction is called a precipitate
A change in which the original substance(s) change into new ones is a chemical change
If bag of popcorn has a mass of 97 grams before popping and 87 grams after popping, how much gas was produced during the change? 10 grams
Why is the law of conservation of mass a "law" rather than a "theory" it describes the behavior of matter, it doesn't explain how or why
A change that cannot be reversed is a chemical change
Matter has a mass of 200g and a volume of 50 mL. What is the density of the matter? What is the state of matter? 4g/mL, liquid
The amount of a substance that can dissolve in another substance is its solubility
solubility is a physical property
Melting point is a size_______________ physical property independent
The amount of matter that makes up an object is its mass
the amount of gravitational force on an object is its weight
Leaves changing colors is an example of a chemical change
An orange flower is an example of a physical property
Why is it important to evaluate a website before using it for research you must validate the information
A property of matter is a trait or characteristic that describes it
A physical property is a property that can be observed without changing the makeup (composition) of the material
A chemical property is a property of matter in which the composition of the material must be changed in order to observe it
A physical property that increases as the size or amount of the object increases is size ____________. dependent
Why is state of matter considered a physical property? the composition doesn't change, just the density of the molecules
The amount of space an object takes up is volume
What is the function of a theory a theory explains how or why something occurs in the natural world
The ability to react with another substance is a chemical property
the tendency to rust or tarnish is a chemical property
the ability to explode is a chemical property
Density describes the relationship between which two properties? mass and volume
Density = mass divided by volume. d = m/v
mass is measured in the unit grams
volume of a liquid is measured in the unit mL
volume of a solid is measured in the unit cm3
How are a property and a change in matter different from eachother? A property describes a characteristic or trait. A change describes a behavior (the object is actually changing in some way)
Sequence the general density of the three states of matter from highest to lowest. solid, liquid, gas
How does heat effect the rate of a chemical reaction It increases the rate (speeds it up)
Matter cannot be created or destroyed is the law of conservation of mass
An orange flower is an example of a physical property

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.
