Difference between physical and chemical change.
A chemical reaction is when you cannot change it back. A physical reaction is when you can reverse it back. For example, if you break a chair leg, you can always put it back together. If you put sugar in water, you can evaporate the water and you will have sugar crystals left.
Physical reactions stay the same and just change shape. For example, the gallium spoon was the same medal just a different shape.
Chemical reactions have explosions like fireworks.
Was my experiment a physical or chemical reaction?
My experiment was a chemical reaction because when you mix it then you can't change it back.
Why is it a chemical reaction
when i did my experiment the soap reacted the fat in the milk and that was why the food coloring was moving
