Write 3 differences between chemical and physical change?
Okay now here goes in a physical change no chemical reaction takes place. in chemical change chemical reactions take place. A physical change is reversible but a chemical change is not.In a physical change no new substance is formed(A+B=B) in a chemical change new substances are formed(A+B=C)
What are various types of change?
Basically there are 3 types on changes in chemisty. 1. Inorganic Changes-reaction of elements and compounds 2. Organic Changes-reactons of mineral oils and its compound. 3. Bio-chemical changes-reactions involves protein, enzyme and hormones.
Contrast physical and chemical changes?
Physical changes are changes that do not alter the chemical composition of a substance, such as changes in state (solid, liquid, gas) or shape. Chemical changes, on the other hand, result in the formation of new substances with different chemical properties. Physical changes are usually reversible, while chemical changes are often irreversible.
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
Turning brownie mix into brownies chemical or physical change?
It is chemical i believe because it is changing its form. here's a tip if you do not no the difference between physical and chemical physical change: 1) atoms do not rearrange (switch patterns). 2)Only physical properties change. Chemical properties do not change. 3)phsical changes are generally easy to reverse. 4)no energy is produced by the substance. example: an ice cube (H20) melts in the sun and turns into water (H20) Chemical change 1)Atoms are rearranged into different molecules. There will be a new chemical formula. 2)both physical and chemical properties are changed. 3)changes are not reversible without another reaction. 4)energy is often produced (fire or heat) 0
