yes stone is an example of matter as matter is defined as anything g that has mass and occupies space.
Q. How can changes in matter be described?
There are two types of change in matter: physical change and chemical change. As the names suggest, physical changes never change the identity of the matter, only its size, shape or state. In a physical change, atoms are not rearranged and the matter’s physical and chemical properties are unchanged.

Q. Is smoke a sign of a chemical change?
Burning is a good example of a chemical change. When we burn wood, it releases energy in the form of heat and creates new substances: smoke and ash. Some signs of a chemical change are: smoking, change in color, change in temperature, bubbling, and fizzing. This is an example of a chemical change.
Q. Is smoke and fire a physical change?
Smoke produced in a forest fire is a sign of a chemical change because it is a new substance that comes from the flammability of the forest.
Q. Is fire a physical thing?
Fire is not a physical thing. Any fire generated is a product of a chemical reaction that releases primarily heat and light and not through a physical…
Q. Is breaking a pencil a physical or chemical change?
A physical change affects the physical properties of the matter but not the particles that make up the matter. Think about a pencil that is broken in half. The broken pencil is still a pencil, but its physical properties, like size and shape, have changed.
Q. Is paper burning a chemical change or physical?
Burning of paper is not a physical change. Ash is formed as result of burning of paper which is a new product. Chemical change a new substance must form. These changes are irreversible in nature.
Q. What type of chemical change is burning paper?
The burning of paper is a chemical change. The paper burns in air to form smoke and ash.
Q. Is mixing chocolate and milk a chemical change?
Answer and Explanation: Chemical change refers to such change which leads to the formation of a product that is totally new in terms of its composition and properties. Thus, mixing chocolate syrup with milk is a physical change as it does not result in change in composition of the constituent substances.
Q. Is Lava turning to rock a chemical change or physical change?
When solid rock changes into its liquid lava state, a physical change has occurred. In a physical change, the particles of a substance rearrange, but do not change into different particles.
