This type of observation always uses numbers

Numbers

Devices used to measure the speed of molecules

Thermometers

Unit of Mass in the SI system

Kilogram

Unit of Volume in the SI system

Liters

Scientists who are using one or more of their senses are doing this

Making observations

Color and texture are two examples of this type of property

Physical

The ability of a material to combuest is what type of property?

Chemical

The term for the temperature at which a liquid becomes a gas

Boiling Point

Most substances undergo this change when heat is added

They expand

This chemical property is present when substances slowly react with oxygen

Rust

Salt dissolved in water would be considered a what?

Mixture

Substances like 24K gold are considered to be what kind of substance?

Pure

The most common mixture found in the atmosphere

Air

These are two or more elements chemically combined

Compounds

These form from 2 or more substances that can be separated easily

Mixtures

Found to the left of the arrow in a chemical equation

Reactants

These are two processes that involve reaction with oxygen

Rust and combustion

Law stating that energy can be neither created nor destroyed

Conservation of energy

The law of conservation of matter dictates that both sides of a chemical equation must do this

Balance

The term for reactions releasing heat or light or both

Exothermic

A push or a pull

Force

This contact force allows an object to float in a fluid

Buoyancy

The force that acts on all objects all the time

Gravity

This is the tendency of an object in motion to stay in motion

Inertia

The force of gravity depends upon these two factors

Mass and Distance

The term for the energy of motion

Kinetic

When you drop a golf ball, this decreases when kinetic energy increases

Gravitational Potential Energy

Plants take radiant energy and convert it to this type of energy

Chemical Energy

Your body converts chemical energy into what type of energy?

Kinetic Energy

To calculate kinetic energy, you must multiply these two factors

Mass and Speed

The process some countries use to kill bacteria and other microbes from food

Ionized radiation
