Why is food darkening a chemical change?
This darkening involve chemical reactions.
What is the chemical change taking place when food is cooked?
Cooking food involves chemical changes like new substances are made, process is irreversible, and an energy occurs. An example is cooking with baking powder, the sodium hydrogencarbonate breaks down when heated and releases carbon dioxide.
Is cooking food is a reversible change?
No, cooking food is not a reversible change. During cooking, chemical reactions occur that alter the food's composition, texture, and flavor, making it impossible to revert to its original state. For example, proteins denature and starches gelatinize, resulting in changes that cannot be undone. Thus, once food is cooked, it cannot be transformed back into its raw form.
Is deep frying chicken a chemical change?
Cooking food (including frying it) does produce chemical changes.
Is water boiling in a pan a physical or chemical change?
It depends on what is boiling. If you are boiling WATER, then it is NOT a chemical change, it is a physical change (change of state from liquid to gas). If you are cooking food on the stove, a chemical change is occuring. That is, the chemical bonds within the food molecules are actually changing. One way you can tell that it is a chemical change is that you can't "uncook" food, but you can condense steam back into water.
What can chemical changes change?
Cooking food can cause chemical Changes
What is one example of a chemical change in your house?

What scientific activities are part of your daily life?
Well, it can be many things .. For example, cooking. When you heat the food a chemical change occurs within the food.
Is it true that food is an example of chemical change?
Not exactly but food, like any gas, liquid or solid, is made up of one or more chemicals. Plants growing is 'chemical change'. Food rotting is 'chemical change' Cooking food is 'chemical change'. Without 'chemical change' or chemical reactions, plants would not exist. Human beings would not exist. Anything we eat would not exist. Planet Earth would not exist!
Why is food darkening a chemical change?
This darkening involve chemical reactions.
Cooking a chemical or physical change?
Both of those processes are parts of cooking. It depends on what you're doing. If you're melting or freezing its a physical change. If you're changing it into another substance then its chemical. A chemical change is when a substance is changed into another entirely different substance. This happens when an event occurs that changes the composition of the substance. Examples of chemical changes are color changes, absorbing energy, releasing energy, odor changes, producing gases, producing solids, and can't be easily reversed. A physical change is when there is a change is physical properties. This happens when an event occurs that doesn't change their chemical. Examples of physical changes are changes in the texture, shape, size, color, odor, volume, mass, weight, and density.

What is an example of a physical and chemical change that you might observe in the school cafeteria?

Is adding food colouring to icing a chemical change?
This is not a chemical change. The food colouring forms part of the mixture on the icing sugar + flavouring + water + colouring. A chemical change requires there to be a change in the nature of the ingredients eg cooking eggs.
How does the process of cooking involve chemical reactions?
When cooking, chemical reactions occur as heat is applied to ingredients, causing molecules to break down and rearrange. This can change the color, texture, and flavor of the food. For example, proteins denature and sugars caramelize, creating new compounds that give food its cooked taste.
