CH Q
How can physical properties help you identify substances?
VOCAB:
particle phase physical change
vapor solid liquid gas

3. particle
phase
physical change
Small pieces or parts
A stage in a process
When the arrangement or distance between particles change; the particles stay the same

4. solid liquid gas vapor firm and stable in shape
substance that flows freely but is of constant volume
air-like fluid substance which expands freely to fill any space available
substance that is a mixture of two phases at room temperature
***vapor has undergone a phase change while a gas did not

5. DISCUSSION
