Mrs. Buchanan - Physical and Chemical Properties and Changes
| Question | Answer |
|---|---|
| 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 |
