Differences of Physical and Chemical change 

# data[].attributes.body
Physical changes can turn into solids, liquids, and gasses. They can also all turn back something chemical changes aren't able to do. Chemical changes it by burning them

# data[].attributes.body
Physical change is when something turns into gas, liquid, or solid and could be altered back.

# data[].attributes.body
Some examples are:

Reactivity with other chemicals.

Toxicity.

Coordination number.

Flammability.

Enthalpy of formation.

Heat of combustion.

# data[].attributes.body
When something gets altered and cant change back. Signs of it is oder, color, and temperature.

Some examples are:

Students requiring adaptations to gain the full benefit of a demonstration may find a worksheet with guided observations useful. Alternatively, a teacher may wish to use a worksheet with guided observations to model what observations all students should be making during a demonstration.
