What is an example of both a physical and chemical change?
Melting and burning of candle wax is an example of both physical and chemical changes.
Answer: Burning of wood is a example of both physical and chemical change.
When wood is burnt the moisture present in it turns to vapour ,it is a physical change while it burns and generate CO2 is a chemical change..
Is mixing ingredients for a cake a chemical reaction?
Simple forms of dissolving and mixing are considered physical changes, but mixing the ingredients of a cake is not a simple mixing process. A chemical change starts to occur when the ingredients are mixed, forming new substances.
What is an example of endothermic?
These examples could be written as chemical reactions, but are more generally considered to be endothermic or heat-absorbing processes: Melting ice cubes. Melting solid salts. … Converting frost to water vapor (melting, boiling, and evaporation, in general, are endothermic processes.
Is frying an egg exothermic or endothermic?
Frying an egg is a chemical reaction. It is an example of an endothermic reaction, or one that takes in heat in order to make the reaction occur.
What is baking a cake?
Cake is a form of sweet food made from flour, sugar, and other ingredients, that is usually baked. … The most commonly used cake ingredients include flour, sugar, eggs, butter or oil or margarine, a liquid, and leavening agents, such as baking soda or baking powder.
Is cooking an egg a chemical change?
Cooking the egg is an example of a chemical change.
What are 3 differences between physical and chemical changes?
A chemical change is a permanent change. A Physical change affects only physical properties i.e. shape, size, etc. … Some examples of physical change are freezing of water, melting of wax, boiling of water, etc. A few examples of chemical change are digestion of food, burning of coal, rusting, etc.
What are 10 physical changes?
Examples of Physical ChangesCrushing a can.Melting an ice cube.Boiling water.Mixing sand and water.Breaking a glass.Dissolving sugar and water.Shredding paper.Chopping wood.More items…•
Is baking a cake a chemical reaction?
Answer and Explanation: Baking a cake is a chemical reaction due to the nature of the ingredients that are mixed together and the addition of heat.
Is cooking a chemical or physical reaction?
A chemical change results from a chemical reaction, while a physical change is when matter changes forms but not chemical identity. Examples of chemical changes are burning, cooking, rusting, and rotting. Examples of physical changes are boiling, melting, freezing, and shredding.
Is baking an endothermic reaction?
Answer and Explanation: Baking bread is an endothermic process. An endothermic reaction is one that must absorb energy, in this case heat, in order to make the reaction…
What type of chemical reaction is baking cookies?
While baking, the heat allows for the sucrose (sugar) to break down into glucose and fructose. This causes a polymer chain which allows for the cookie to have a light brown, shiny crust. When the sodium bicarbonate (baking soda) absorbs heat, a chemical reaction occurs – 2NaHCO3 –> Na2CO3 + H2O + CO2.
