States of Matter
100
What is matter?
anything that has mass and takes up space
100
Explain how you would find the mass of an object and what are the units on the number?
Use a balance and grams.
100
Is the picture of an element, compound or mixture? Explain.
Element because it's made of only one type of atom.
100
You have a drop of water (H2O)....... Explain it using the word atom.
Water is made of two types of atoms, hydrogen and oxygen.
100
Explain the movement of molecules from slowest to fastest using the three states of matter.
In a solid they move the slowest then a liquid and fastest in a gas.
200
What is mass?
the measure of how much matter is in an object
200
Explain how you would find the weight of something.
use a scale
200
Is the picture of an element, compound or mixture? Explain.
Mixture because there is more than one type of material in the substance.
200
You have a drop of water (H2O)....... Explain it using the word molecule.
What is a molecule where oxygen and hydrogen are bonded together.
200
Explain the distance between the molecules.
Solid close together. Liquid farther apart. Gas the farthest apart.
300
What is weight?
The downward pull of gravity on an object.
300
What is the volume of a rectangular solid that has a length of 8 cm, a width of 10 cm, and a height of 5 cm? (write the formula first)
V = LxWxH V= 8cmx10cmx5cm V= 400 cubic cm
300
Explain what a pure substance is.
It is a substance that has only one type of material that it is made of.
300
You have a drop of water (H2O)....... Explain it using the word element.
Water is made of two elements combined.
300
Describe the shape of each state.
Solid is a fixed shape. Liquid and gases are not fixed and take the shape of their container.
400
What is volume?
the amount of space an object takes up
400
Explain how you would find the volume of a solid that is not a rectangular solid.
Water Displacement
400
How is an element and a compound different?
An element is made of the same atom. A compound is more than one atom bounded together.
400
You have a drop of water (H2O)....... Explain it using the word liquid.
Water at room temperature is in the liquid form.
400
Describe the volume of each state.
Solid and liquids have a fixed volume. Gases do not have a fixed volume.
500
What is an atom?
the smallest basic unit of matter
500
Find the density of an object that has a volume of 10 cubic cm and a mass of 80 grams. Write out the formula first.
D = mass / volume D= 80 grams / 10 cubic cm D = 8 g/cubic cm
500
What is a molecule and give an example of one.
Two or more atoms bounded together.
500
You have a drop of water (H2O)....... Explain it using the word pure substance.
Water contains the same type of molecules throughout so it's a pure substance.
500
Do you need to increase or decrease the energy in each of the three situations: A. Gas to Liquid B. Solid to Liquid C. Liquid to Gas
A. Decrease B. Increase C. Increase
