A carcinogen is anything that causes cancer in humans or animals. Carcinogens can be chemical or physical agents or radiation. Chemical carcinogens include molecular substances that are found in a variety of different compounds, such as cigarette smoke and some pesticides; physical carcinogens are particles of soft or hard material that are not soluble in water. They exist as a solid compound. Ionizing radiation is an example of a radioactive carcinogen, as is found in UV light and medical x-rays
the difference between a physical change and a chemical change is that a physical change is usually reversible whilst a chemical change is not reversible.

The diffence between chemical and physical is that ones chemical and ones physical!!
A physical change is reversible, a chemical change is not.
a physical change is reversible but a chemical change is irreversible
a physical change is reversible but a chemical change is irreversible
You can tell the difference by knowing that a physical property changes shape and that a chemical property changes the substance.
it can bereversible and
Your telling me!
A chemical change is when the chemical properties of a substance changes and a physical change is when the chemical properties stay the same but the physical properties (shape, temperature etc...)
the difference is chemical can change it and it cant go back to normal. physical is when u can put it back.
