What are changes happen to the food?
Food undergoes physical, chemical, and biological changes during storage and preparation. Physical changes may include freezing, heating, or grinding. Chemical changes involve oxidation, browning, or fermentation. Biological changes occur when microbes grow and spoil the food.
Are most chemical changes seen or not seen?
Most chemical changes happen between molecules, so they are unseen.
Do chemical changes only happen at a heigh temperature?
No, chemical changes can occur at various temperatures depending on the specific reaction. While many chemical reactions do happen at higher temperatures to provide enough energy for the reaction to occur, there are also reactions that occur at lower temperatures. Temperature is just one factor that can influence the rate of a chemical reaction.
What are the different changes around us?
Changes occur everywhere, every moment around us. Everything in the world is subject to change. There are five types of changes. 1. Chemical and physical changes. 2. Reversible and irreversible changes. 3. Desirable and undesirable changes. 4. Periodic and non-periodic changes. 5. Slow and fast changes. Chemical changes: That change the chemical composition of the material. Physical change: That are temporary and do not change the chemical composition of the material. They change only the state, colour, and texture. Reversible chages: They can be reversed. Irreversible changes: They cannot be reversed. Desirable changes: Which are desired Undeirable changes: Which are'nt desired. Periodic changes: Which happen after a regular intervals. Non-periodic changes: Which happen irregular of any specific interval time. Slow changs: Which take a long time to occur. Fast changes: Which happen quickly. -Param Gupta, Std. 6, Victorious Kidss Educares

Is a fire a physical or chemical change?
A fire is a chemical change due to the irreversible changes that happen.
What is one way that a chemical change can happen in a household?
Cooking involves chemical changes.
What are examples of chemical changes that happen in your environment?
volcanic eruption
What are chemical changes in chocolate?
Chemical changes in chocolate occur when it is heated, leading to the melting of cocoa butter and the release of aroma compounds. When chocolate is tempered, the crystalline structure of cocoa butter is altered to give it a shiny appearance and a crisp texture. Additionally, during the Maillard reaction, sugar and proteins in chocolate interact under heat to produce new compounds that enhance flavor complexity.
