Gas
•Definite Shape – No, it fills whatever shape it is put into•Definite Volume –No, Gas can fit into
whatever volume you can push it into (Tank of Helium Gas)• Take the Shape of the Container:
YES….and FILLS it!
Liquid

Liquid
•Definite Shape – No, it conforms but does not always fill the container•Definite Volume –Yes, liquid always has the same volume•Take the Shape of the Container: YES

Solids•Definite Shape – Yes, most often has a
specific form•Definite Volume –Yes, ALWAYS fills up the
same amount of space (volume)• Take the Shape of the Container: looking
at the smallest unit part, solids most often do not take the shape of their container.
• *this does not include things such as clay, putty, etc.
Endo vs. Exo
Type of Change Definition Heat(in or out)
Temperature(up or down)
Endothermic(photosynthesis)
Exothermic(combustion)
Heat is added for the reaction or change to occur
inup
Heat is released from the reaction
