Physical properties
conductors of electricity and heat, can be shaped into sheets, can be shaped into sheets or wire, solids, have gray color, can reflect light, shiny
Liquid and Gas
Physical changes may happen more or less easily depending on temperature. Example: Butter is easier to spread when it is warm.
Solute
Cut it into pieces, peel the skin, etc.
Particles move faster as the temperature rises, they can rearrange themselves into new substances quickly.
Chemical Change
when different materials are placed together but each material keeps it's own properties(can be separated)
You bake a cake with it
Solution
The atoms are connected differently
The particles are packed closely together, they do not move, just vibrate
Atomic Theory
Answers will vary. Example: Cheerios, strain the cereal from the milk
The medicine in the bottle may change if it is heated.
