Are phase changes physical or chemical in nature?
Phase changes are physical changes in nature. They involve a change in the state of matter (solid, liquid, gas) rather than a change in the chemical composition of the substance. Heating or cooling a substance can trigger phase changes.
Is a baking chocolate cupcakes chemical or physical?
Baking chocolate cupcakes involves both chemical and physical changes. Physical changes occur when ingredients are mixed, the batter changes texture when heated, and the cupcakes rise in the oven. Chemical changes take place when the cupcakes bake, as the ingredients react to produce new compounds and the cupcakes change color and flavor.
Does matter always retain it's original state?
No, matter can undergo physical or chemical changes that alter its original state. Physical changes involve a change in state without altering the chemical composition, while chemical changes involve reactions that result in the formation of new substances with different properties.
Is digestion of food physical change or chemical change?
Digestion of food is a combination of physical and chemical changes. Physical changes occur as food is broken down into smaller pieces through chewing and grinding. Chemical changes take place as enzymes in the digestive system break down food into simpler molecules that can be absorbed by the body.
What occurs when a chemical reacion takes place?
fizzing, bubbling, gas, odors, a new substance always is formed once a chemical reaction takes place. but it depends on what is being reacted to determine what reaction is going to take place.
When do atoms form chemical bonds?
Always get ready to give or take energy to get stability.
Do chemical changes take place when a mixture is made?
No!chemical changes do not take place when a mixture is made.The constituent substances of the mixture retain their own chemical composition.Thus only physical changes take place.
Are phase changes physical or chemical in nature?
Phase changes are physical changes in nature. They involve a change in the state of matter (solid, liquid, gas) rather than a change in the chemical composition of the substance. Heating or cooling a substance can trigger phase changes.
What energy changes take place in a car engine?
chemical
What changes take place in copra during storage?
chemical
Does a chemical change create a temperature change?
Almost all chemical changes release or take in energy, and thus do result in changes in temperature.
What is meant by thermodynamics of a chemical reaction?
It refers to the energy changes that take place during a chemical reaction.
What chemical changes take place as food is being digested?
ewan
What are facts about change?
Chemical changes take place on the molecular level
Is baking cake a physical change or chemical change?
Baking a cake involves both physical and chemical changes. Physical changes occur when the cake batter changes form (such as turning from a liquid to a solid). Chemical changes occur when the ingredients react with each other during baking, leading to the formation of new substances that give the cake its flavor and texture.
Are changes that occur in mixtures and solutions physical or chemical?
chemical,because if you combined them you can't take it back out so it is in there for good so it is chemical
What are facts about physical and chemical change?
Chemical changes take place on the molecular level
