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.

Is grinding salt a chemical or physical change?
physical
If crushing a rock is a physical change what type of change does buring a candle create?
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.
Is a erosion caused by wind a chemical change?
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.
Is the rock cycle a chemical change or physical change?
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.
Is stone breaking a physical change?
Breaking of stone is a physical or chemical change? Explain.
What is crushing a rock a chemical or a physical change?

What type of physical change will while crushing a rock and burning a candle?
1. Crushing is a physical process.2. Burning is a chemical process.
Is crushing rocks a physical change?
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.

When molten rock cools and hardens is a physical change or chemical change?
When molten rock cools and hardens, it is a physical change because the composition of the rock remains the same. The change in state from liquid to solid does not alter the chemical makeup of the rock.
Is rock broken into small pieces a chemical change?
No, breaking rock into small pieces is a physical change because the chemical composition of the rock remains the same. It is merely a change in the physical appearance of the rock.
Is a rock getting melted into magma a chemical reaction?
No, the process of a rock melting into magma is a physical change, not a chemical reaction. The change is due to an increase in temperature causing the rock to undergo a phase change from solid to liquid.
What are effects of physical and chemical change on health and environment?
rock
Is landslide physical or chemical change?
