Physical change because the two substances do not bond together. If you waited for a long time the water and the food coloring would separate.
Yes, because the chemicals within the substances do not change to create a new substance.
No, spilling water is a physical change, not a chemical change. A chemical change involves a change in the chemical composition of a substance, whereas spilling water only changes its location and physical state.
Mixing salt and water is a physical change, not a chemical change. The salt does not change its chemical composition when it dissolves in water, only its physical state.
This is a physical change. The bubbles are pockets of steam which is the same chemical as water, just in a different state.
It is a physical change.
Physical because we can still seperate the particles
When food coloring is added to water, it is a physical change. This is because the food coloring dissolves in the water, creating a homogeneous mixture without altering the chemical composition of either the water or the food coloring. The change is reversible, as the colored water can eventually be separated back into its components through methods like evaporation.
Physical, the water is still water and the food coloring is still food coloring you just mixed them together in one space. If you waited long enough the food coloring and water would settle back out so you had just water and food coloring.
Yes, because the chemicals within the substances do not change to create a new substance.
Physical
Adding food coloring to a mixture would be considered a physical change. There are no new chemical bonds formed or broken. What you are creating is a new solution, just like adding salt to water and it dissolves. The salt stays salt, the water stays water. In this case what you are dissolving has a color to it so it changes the color of whatever you add it to but fundamentally the molecules that make up the food coloring stay the same.
Boiling water is a physical change because it does not change the chemical composition of the water.
Ocean water is a substance, not a physical or chemical change.
Wrong
Carving pumpkin physical change or chemical change
No, spilling water is a physical change, not a chemical change. A chemical change involves a change in the chemical composition of a substance, whereas spilling water only changes its location and physical state.
Condensation of water is a physical change.
