Physical and Chemical Changes
Clues that helps me identify Chemical changes
Produces odor, smell, gas, light, sound, changes color
Release or absorb heat
Atoms are changed into a new substance by adding protons, neutrons, or electrons
Creates new substances
Temperature change, explosions, or bubbles and fizzes
Differences between Physical and Chemical Changes
Physical changes can usually be seperated or undone, even if it is very hard, when chemical changes usually cannot be undone or seperated
Physical changes is when the substance doesn't change, only the size or shape changes, while chemical changes is when the substance changes
Physical changes usually only changes shape or size, while chemical changes include releasing or absorbing heat, producing odor, smell, gas, light, sound, or change color
Chemical changes may cause temperature changes withour heating or cooling, or causing an explosion or bubbles
Also, physical changes can also happen in matter. Physical changes are changes that usually can be seperated or undone, even if it is very hard to.
Physical changes may cause that object to change size or shape, but does not change the substance, even if it looks different.
A physical change is when the substance doesn't change, it is still the same thing, but the form may be changed or transformed into another thing, but still is or made of the same substance.
Examples for Chemical Changes
Cake baked in an oven
Cookies burned in an oven
Wood burned into ashes, producing smoke, smell, and light, the fire
Baking soda mixed with vinegar
Examples for Physical changes
Water frozen into icicles at winter
Icicles that melted into water in spring
Apples smashed in a blender and turned into apple juice
Glass mini sculpture dropped onto the floor and shattered into tiny pieces
Wood turned into paper
Sugar or added into a drink, like coffee, chocolate, or tea

It also can make and release, or let out heat, or absorb heat.
The particles of each substance are melted together to make a new substance, or, thing.
Chemical Changes are substances melded or melted together, with heat, that usually cannot be seperated or undone.
It can or may also produce odor and smell, gas, light, sound, or even change color.
Atoms change into new substances by adding protons, neutrons, or electrons
May cause an explosion or make bubbles
Does chemical changes have to include those changes that the videos said?
Are there any changes that aren't chemical or physical, or possibly both?
What changes happens when soda is shook? I think it's chemical, because it fizzed and bubbled, and caused an "explosion"
Didn't see or hear any, don't have any
