What are the three states of matter?
Liquid, Solid and Gas
100
What is volume?
This is measure of the size of a body or region in three-dimensional space
100
What is mass?
Mass is a measure of the amount of matter in a object
100
What is density?
Density is the ratio of the mass of a substance to the volume of the substance.
100
What is weight?
Weight is a measure of the gravitational force on a object
200
What is matter?
Matter is anything that has mass and takes up space.
200
How do you read the volume of a liquid using a graduated cylinder?
You measure the volume of a liquid by looking at the bottom of the meniscus.
200
What is the difference between mass and weight?
mass is the amount of matter in a object, while weight is amount of gravitational force exerted on a object
200
What is the formula for density
D= m/v
200
What would the rusting of any metal be considered?
It would be considered a chemical change.
300
What does all matter do?
they take up space.
300
What is a meniscus?
A meniscus is the curve at the liquid's surface by which one measures the volume of the liquid.
300
Does the mass of an object ever change depending on where your located?
No it will always stay the same no matter where your located.
300
Why is density use to identify objects?
The density of an object is always the same at a give pressure or temperature.
300
What type of change would fireworks be considered?
Chemical Change
400
Why do you think astronomers use the term dark matter?
They use the term "dark matter" because it refers to the matter we cant see
400
What are two units used in the measurement of the volume of a liquid?
Liters and Milliliters
400
How can you change the mass of an object?
The only way to change the mass of an object is to change the amount of matter that makes up the object.

Gasoline is a non polar liquid that will float on water. 450 grams of gasoline is spilled into a puddle of water. If the density of gasoline is 0.665 g/mL, what volume of gasoline is spilled?
680 mL

A chemical reaction that takes in heat energy during the reaction is called:
endothermic
500
Using what unit do you measure vapor pressure?
Using Kilo pascals.
500
How would you measure the volume of a 12 sided object?
Using the water displacement method
500
What does the gravitational force between an object and the earth depend on?
It depends on the objects mass.

My gas tank in my car has a total volume of 68 L. The manual says the gas gauge light will come on when there are only 5 L remaining in the tank and that the car will not be able to draw on the last 2 L in the tank. Practically speaking, what is the functional volume of the gas tank? If I ran out of gas, the car won't go, and I put in 5 L of gas, what is the total volume of gas in my tank? If 5 L of gas has a mass of 450 Kg, what is the mass of the gas in my tank? What is the density of the gas?
D = m/v functional volume of tank is 68L - 2 L = 66 L gas "empty tank" + 5 L = 7 L gas m = 630 Kg D = 9.0 x 101 g cm3

Diane draws a picture on a piece of paper and then folds it into a paper airplane. She throws it at her little brother, and its hits him in the head. He responds by ripping up the paper. Which of the following is an example of a physical change?
ripping up the paper, folding the paper into an airplane, drawing on the paper
