Do not try this without the assistance of an adult. Check with your teacher or parent first!
Styrofoam is a trademark name for polystyrene thermal insulation.
Pure solid polystrene is a colorless, hard plastic with limited flexibility. Most of the time it is expanded with 90%- 95% polystrene and 5%-10% gaseous blowing agent with heat or steam.
We poured actone over a styrofoam cup. What happened to the polymer?
Is it a physical change?or…a chemical change?
Remember:
A chemical change is defined as changes substances under go when they become new or different substances.
To identify a chemical change look for observable signs such as color change, bubbling and fizzing, light production, smoke, and the presence of heat.
A physical change occurs when objects undergo a change that does not change their chemical nature.
A physical change involves a change in physical properties, and can be observed without changing the type of matter.
To identify a physical change look for differences in texture, shape, size, color, odor, volume, mass, weight, and density.
