What else can I help you with?
Is drying a hydrate a physical or chemical process?
Drying a hydrate is a physical process. It involves the removal of water molecules through methods such as heating or desiccation without changing the chemical composition of the compound.
Is hanging wet towels a chemical or physical change?
It is a physical change. Being changed from wet to dry.
Is mechanical weathering a chemical process?
No, mechanical weathering is a physical process that breaks rocks down into smaller pieces without changing their chemical composition. On the other hand, chemical weathering involves the alteration of a rock's chemical makeup through processes like oxidation or dissolution.
What of these does not cause physical weathering?
Chemical weathering does not cause physical weathering. Chemical weathering refers to the breakdown of rocks through chemical reactions, while physical weathering is the process of breaking down rocks into smaller pieces without changing their chemical composition.
A way that water can go through a physical change?
by changing from liquid to solid
How do you use the word physical weathering in a sentence?
weathering that breaks down rocks by contact without changing the mineral coment of the rock
What is changing the shape of rocks called?
The process of changing the shape of rocks is called weathering. This can happen through physical processes such as erosion, abrasion, or cracking due to temperature changes, and chemical processes such as dissolution or oxidation.
Which physical process weathers rock?
Physical weathering is the process by which rocks are broken down into smaller pieces without changing their chemical composition. This can occur through processes such as freeze-thaw cycles, abrasion from wind and water, and root wedging by plants.
What is changing by contact?
Changing by contact refers to a process involving physical or chemical contact that results in a transformation or alteration of a substance or object. This could involve changing a material's properties or composition through direct interaction with another element.
Why is sublimation of iodine is a physical process?
Sublimation is a physical process because it involves the direct transition of a substance from solid to gas phase without passing through the liquid phase. In the case of iodine, when it is heated, it directly converts from solid to gas without changing its chemical composition, making it a physical change.
What process of weathering?
Weathering is the process of breaking down rocks and minerals on Earth's surface through physical, chemical, or biological means. Physical weathering involves the physical breakdown of rocks into smaller pieces without changing their chemical composition, while chemical weathering involves the transformation of rocks through chemical reactions. Biological weathering refers to the breakdown of rocks by living organisms such as plants and animals.
What is another term used to described physical weathering?
Another term used to describe physical weathering is mechanical weathering. This process involves the breakdown of rocks into smaller pieces without changing their chemical composition, usually through physical forces like ice, water, and wind.
