Grinding something is an example of a physical change, because you are not chemically changing what the substance is, you are only changing the form of it. Another example of a physical change is boiling water, because the water is still water, it's just in a gas form instead of liquid.
When something is grinded it is a physical change not a chemical change.
Crushing a rock is a physical change because the chemical composition of the rock remains the same even though its physical appearance changes.
Crushing a rock does not change the chemical identify of it's constituent compounds. Therefore, crushing a rock is a physical change.

Burning a candle is a chemical change, as it involves a chemical reaction where the wax and oxygen combine to produce carbon dioxide, water vapor, and energy in the form of heat and light. This change is irreversible and creates new substances.
No, erosion caused by wind is a physical change, not a chemical change. The wind is simply moving particles of rock or soil from one place to another without altering their chemical composition.
The rock cycle involves both physical and chemical changes. Physical changes involve processes like weathering and erosion that break down rocks physically. Chemical changes occur when minerals in the rocks react with water or gases to form new minerals.
Breaking of stone is a physical or chemical change? Explain.
Crushing a rock is a physical change. It is still rock, just in smaller bits.
1. Crushing is a physical process.2. Burning is a chemical process.
Yes, crushing rocks is considered a physical change because the rocks are broken down into smaller pieces without changing their chemical composition. This process can be reversed by reassembling the pieces back together.
physical
When the chemical composition of a rock changes, it undergoes a process called metamorphism. This can happen due to high pressure, temperature, or the presence of chemically active fluids, causing minerals in the rock to recrystallize into new forms. The original rock's minerals may be altered or new minerals may form, resulting in a different appearance and texture.

I think it is physical but I do know it is an igneous rock
Physical Weathering: is when a rock is broken into smaller and smaller pieces. Chemical Weathering: is when the rock change due to different chemical reactions.
The process of a dinosaur bone turning into rock over millions of years is a chemical change. This transformation involves the replacement of organic materials in the bone with minerals through a process called fossilization, altering the composition of the original bone.
rock
No actually it isn't. Breaking a bone is a physical change. Think about it. Are you changing it into a different substance. No you're not, so it's a physical change.
Physical. It is still dirt/rock, no change to it's nature- just its position.
