Physical Properties of Matter
These are properties of matter ,like color and density, that help us classify or identify them
what are physical properties of matter
This is the layer of the atmosphere closest to Earth's surface.
What is the troposphere?
This is anything that has mass and volume.
What is matter?
This/These appear to the right of the arrow/equal sign in a chemical equation.
What is/are the product(s)?
Why does hail form in tall clouds?
Hail starts out as raindrops. It gets pushed high into the atmosphere by wind, where it freezes and turns into ice. It builds up in layers of ice until the ice is so big, it falls to the ground as hail. The clouds need to be tall so the ice can go high into the atmosphere.
The method of finding the volume of an irregularly shaped object?
what is water displacement?
This is the layer of the atmosphere where jet planes normally fly.
What is the stratosphere?
The smallest particle of an element that still has the properties of that element is called this.
What is an atom?
This/These appears to the left of the arrow/equal sign in a chemical equation.
What is/are the reactant(s)?
At what time of year do most thunderstorms and hurricanes occur in the U.S.? Why?
Thunderstorms and hurricanes occur mostly occur in summer in the U.S. This is because both storms need intense heat to form, and when it hit the U.S., it would still need to be hot enough to stay a hurricane.
The pull of gravity on mass
What is weight?
This layer is where harmful rays from the Sun are absorbed.
What is the ozone layer?
This state of matter has a definite shape and a definite volume.
What is a solid?
This type of reaction occurs when two or more elements chemically combine to form a new one.
If the reactants in a chemical reaction include six elements, what can you infer about the product?
I can infer that the product will have the same six reactants, and the same amount of atoms of each element. This is because all chemical reactions are balanced, meaning that there are the same elements on both sides, and the same amount of atoms of each element.
This is equal to an object's mass divided by its volume
What is density?
This is the second outermost layer of the atmosphere.
What is the thermosphere?
This state of matter has no definite shape, but it has a definite volume.
What is a liquid?
This type of reaction releases energy such as light or heat.
What is an exothermic reaction?
If a solution has a pH of four, what can you infer about it? Why?
I can infer that it is an acid, and that it tastes sour. I can also infer that when it combines with a base, it forms salt. Also, it turns blue litmus paper pink or red, and it turns red cabbage juice pink. This is because anything with a pH <7 is an acid, and acids have the properties mentioned.
This principle states that buoyant force is equal to the weight of the fluid that is displaced
What is Archimedes' Principle
This is the outermost layer of the atmosphere where the air is very thin.
What is the exosphere?
This is the state of matter with the most energy.
What is plasma?
This states that during a chemical change, mass is not created nor destroyed, rather it is converted.
What is the law of conservation of mass?
How does increased heat affect the three states of matter?
Increased heat changes the states of matter. This is because when you add heat the particles move faster and farther apart. Most substances would expand, but some, like water, do not.
