300
A substance that moves freely
What is a fluid?
300
A change in which energy is taken in by a chemical reaction, for example when you mix baking soda and vinegar
What is an endothermic change?
300
The measure of the force of gravity on an object. It can change with a change in location
What is weight?
300
Elements that are found combined with other elements in a specific ratio

300
The two types of vaporization
What are evaporation and boiling?
400
The particles in a solid substance are vibrating so fast that they break free from their fixed positions
What is the melting point?
400
A change in which energy is release by a chemical reaction, for example when you mix water and calcium metal
What is an exothermic change?
400
Equal to a millimeter
What is a centimeter cubed?
400
A mixture that you can identify its different components such as a fruit salad
What is heterogeneous mixture?

Why does the evaporation of sweat cool your body on a warm day?
In order for your sweat (a liquid) to evaporate (into a gas), the particles need more thermal energy. The energy comes from your body. When the heat from your body is used to evaporate sweat, it makes you feel cool.

Solids can be identified two ways by particle arrangement
What is a crystalline solid and amorphous solid?
500
Any change in a state of matter
What is physical property?
