Now i will tell you what physical changes are. Physical changes occur when objects undergo a change that does not change their chemical nature. A physical change involves a change in physical properties.
Physical properties can be observed without changing the type of matter. Examples of physical properties include: texture, shape, size, colour, odour, volume, mass, weight, and density. An example of a physical change occurs when making a baseball bat. Wood is carefully crafted into a shape which will allow a batter to best apply force on the ball. Even though the wood has changed shape and therefore physical properties, the chemical nature of the wood has not been altered. The bat and the original piece of wood are still the same chemical substance. In my next post, i will tell you on different examples of chemical changes and physical changes.
