Polaris, also known as Alpha Ursae Minoris, is primarily composed of hydrogen and helium, with hydrogen making up about 90% of its mass and helium around 9%. The star also contains trace amounts of heavier elements, such as carbon, nitrogen, oxygen, and metals like iron. As a supergiant star, Polaris has undergone nuclear fusion processes that have altered its composition over time, particularly in its core.

What is the diffence between physical and chemical properties as well an physical and chemical changes?
Physical properties can be observed without changing the chemical composition of a substance. Chemical properties can only be observed by changing the chemical composition of the substance. In a physical change, the chemical composition of the substance does not change. In a chemical change, the chemical composition of the substance changes.

What is weathering that does not alter the chemical composition of the rock called?
The type of weathering that does not alter the chemical composition of the rock is called physical weathering. The acid weathering usually alter the chemical composition of a rock.
