Chemistry Final Review

What is Chemistry?

• The science that investigates and explains the structure and properties

  of matter

• The study of animals and living things

• The physics of Earth and the Solar System

• The use of mathematics to determine the Earth

What is matter?

• The measure of mass that an object has

• Anything that takes up space and has mass

• A form of energy

• The measure of energy

What is mass?

• Measure of the amount of matter an object contains

• The amount of space an object takes up

• The energy of the sun

• The physical change of plants

Which is NOT an example of something that is matter.

• Heat

• Light

• Sound

• Taste

What is the unit of mass in the metric system?

• Kilogram

• Joules

• Cups

• Celsius

If aspirin and sugar contain the same elements (carbon,

hydrogen, and oxygen), why don’t they have the same

properties?

• Because one is aspirin and one is sugar

• They are too much alike

• Their chemical structures are different

• One is a liquid and one is a solid

How do you determine the properties of an object?

• By measuring it

• By examining and manipulating it

• By looking it up

• By opening it up

What kinds of manipulations help us identify what an object is

made of?

• Examining the shape and size

• Listening to the sound it makes

• Measurements and observation of chemical changes

• Feeling the texture of the object

What is the difference between the macroscopic view and the

submicroscopic view?

• Macroscopic is so small that it can only be seen under a microscope.

• Macroscopic is large enough to be seen under normal conditions.

• Submicroscopic is so small that it can’t be seen with a powerful

  microscope.

• Submicroscopic is large enough to be seen normally.

What is a scientific model?

• A device that measures the temperature

• Thinking device that helps you understand and explain macroscopic

  observations, based on experimentation

• A device that measures the weight

• A device that is used like a microscope to look at things
