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 it excavating of soil is chemical change?
Earthquakes are the result of physical changes. As the tectonic plates located at fault lines grind past each other, tension is released in an elastic rebound and an earthquake occurs.
Is cutting of tree a chemical change?
No. Trees' leaves change colors beacuase when winter comes around, they will not have the energy to keep leaves, so they seal off the leaves from the rest of the tree. When the leaves are cut off from the rest of the tree, the chlorophyll in them dies, and turns brown.
The difference between a physical and a chemical change?
A physical change the chemical compounds remain the same in the change, in a chemical change the chemical compound changes. A good example is if you move a raw egg around in a pan, some of the egg may separate but it's still a raw egg. If you turn on the heat and cook the egg you are chemically changing the egg and it so no longer a raw egg.
Is flexability physical or chemical?
it is a chemical property because it can move around and move in any direction.
What are some examples on physical and chemical changes around us?
Some examples of physical changes: * The change of a system from fluid into gas. (Solid into fluids, etc... are also possible) * Deflection of light (optics). * Gravitational force * Magnetism (compass comes to mind) * ... Chemical changes: * Sour rain * Rusty iron (oxidation) * A lot of industrial processes are based om chemical reactions, such as the production of soap. * ... Can someone verify this answer? I'm not a native English speaker, so I might've made some mistakes.
What are some chemical reactions that occur around the house?
They occur often in the kitchen and especially the bathroom. Some of the Chemical changes in a kitchen are: Baking a cake Striking a match Burning toast Spoiling milk Sugar dissolving in tea Printing baking a cake is not an example of chemical its physical
What is the differences between a physical and chemical change in a candle?
The physical change will keep the atoms the same not moving but the chemical change will make it move around with energy.
Is Mercury melting at -39 degrees celsius a physical or chemical property?
physical. you didnt chance the substance atomically. you just melted it
What are the evidences of physical change?
* change shape * change state(solid liquid and gas) and * change sizes
Is the cutting of trees a physical or chemical change?
The act of cutting the tree is a physical change. However, there are chemical changes that take place as a result of cutting the tree. All plants have an ability to "feel" when they are being damaged and the plant cells around the damaged ones stiffen to attempt to prevent further damage.
Is a cooking eggs physical or chemical change?
This is a chemical change. Remember: An easy way to determine whether or not a change is chemical or physical is to ask if the process is reversible. Take the evaporation of water into account. When water evaporates, it can condense back into liquid water. It can be reversed because it is a physical change. Chemical changes are often permanent. Take the burning of wood, for example. This is a chemical change. Once you light wood on fire, it turns into gas. Only the trees and plants around you can take this gas and through photosynthesis, turn it back into wood. So it is a non-reversible process, and is a chemical process.
