What is the difference between chemical and physical processes?
The difference between a physical reaction and a chemical reaction is composition. In a chemical reaction there is a change in the composition of the substances in question in a physical change there is a difference in the appearance smell or simple display of a sample of matter without a change in composition.

What is a physical change example?
Examples of physical change include changes in the size or shape of matter. Changes of state for example from solid to liquid or from liquid to gas are also physical changes. Some of the processes that cause physical changes include cutting bending dissolving freezing boiling and melting.
What is the meaning of chemical processes?
In a scientific sense a chemical process is a method or means of somehow changing one or more chemicals or chemical compounds. Such a chemical process can occur by itself or be caused by an outside force and involves a chemical reaction of some sort.
Is evaporation a physical process?
The evaporation of water is a physical change. When water evaporates it changes from the liquid state to the gas state but it is still water it has not changed into any other substance. All changes of state are physical changes.

What are the physical processes that control the global climate?
What happens in the global climate is mainly determined by a few fundamental processes: incoming solar radiation characteristics of the earth’s surface the atmosphere’s ability to retain heat and the reflectivity of the atmosphere and the earth’s surface.
Evidence of global climate change/warming includes widespread increases in average air and ocean temperatures accelerated melting of glaciers and rising sea level.
What physical processes affect the atmosphere?
Atmospheric processes such as radiation convection and aerosol movement play important roles in shaping the Earth’s energy and water cycles.
How is breathing a physical process?
The process of breathing or respiration is divided into two distinct phases. The first phase is called inspiration or inhaling. When the lungs inhale the diaphragm contracts and pulls downward. At the same time the muscles between the ribs contract and pull upward.
Is breathing physical or chemical?
Is breathing a chemical change or physical change? Breathing is a chemical change as during breathing oxygen is taken inside and carbon dioxide and water are released.
What is the process of respiration in humans?
The lungs and respiratory system allow us to breathe. They bring oxygen into our bodies (called inspiration or inhalation) and send carbon dioxide out (called expiration or exhalation). This exchange of oxygen and carbon dioxide is called respiration.
What are examples of physical pollutants?
What are some examples of physical and chemical changes?
Examples of physical change include cutting paper melting butter dissolving salt in water and breaking glass. A chemical change occurs when matter is changed into one or more different types of matter. Examples of chemical changes include rusting fire and overcooking.
