Is a solution a chemical or physical?
A solution is a material not a change; dissolving is a physical process.
What name do we give temporary changes toa material?
Temporary changes to a material are referred to as "physical changes." These changes alter the state or appearance of a material without affecting its chemical composition, such as melting, freezing, or dissolving. Unlike chemical changes, physical changes are usually reversible.
Is evaporation considered a chemical or physical change?
Evaporation is considered to be a physical change. The chemical nature and identity of the evaporated material is the SAME as that of the liquid.
What is the term for dissolving medium in the solution?
Solvent is the term for a dissolving medium in a solution. The material which is being dissolved is called the solute.
Is eggs turning into omlettes a physical or chemical change?
It is chemical because the nature of the chemical has changed.Physical changes including chopping, grinding, dissolving, melting, freezing, and boiling. An omlette cannot be turned back into an egg. The egg protein has changed its chemical nature. Physical change alters the form or appearance of a material without changing the chemical composition.
How are a solute and a solvent different?
A solute is a material that is soluble meaning it is the material being dissolved. A solvent is the material (usually a liquid) doing the dissolving.
What three ways will speed up the dissolving process?
1. You can stir it 2. You can heat it up so it boils 3. You can crush the material you are dissolving.
How is evaporation considered to be a physical change and not a chemical change?
There is no electron rearrangement when a material evaporates, which is what defines a chemical change. Evaporation is the material's vapor pressure overcoming the particular force (Van der Waals, etc) that otherwise keeps it a liquid.
What is the vapor pressure on the Material Safety Data Sheet for a chemical or solution that is considered an explosive hazard?
The pressure is greater then 10 mm.
How do stream erode channels?
lifting their loose particles by abrasion,grinding and by dissolving soluble material
Is flamability a physical or chemical property?
Flammability is considered a chemical property because it involves how a substance will react with oxygen in a combustion reaction to produce heat and light. It is related to the chemical structure and composition of the material.
Material that have left their origina contianers considerdto be?
Hey! I just learned this in chemistry- as soon as your chemical leaves the original container, it is considered contaminated.
