Intro to Chemistry Test Review

What is Chemistry?

• The study of matter - what its made of and how it reacts with other matter

• The study of life - plants, bacteria, viruses, genetics, etc.

• The study of forces and energy and the universe

• The study of the Earth and its atmosphere - weather, geology, etc.

Select EVERYTHING needed in order for something to be matter

• it must have mass

• it must take up space

• it must be hot

• it must be something we can see

What is an example of matter?

What is something that is NOT matter?

What is an example of macroscopic chemistry?

• studying how sodium atoms and chlorine atoms fit together to make salt

• studying how water molecules stick together

• observing how when salt is added to water it dissolves

• learning how water molecules pull apart salt molecules when mixed

What is an example of microscopic chemistry?

• observing how different temperature of water dissolve different amounts of salt

• observing how salt water conducts electricity

• observing how when salt is added to water it dissolves

• learning how water molecules pull apart salt molecules and why dissolving happens
