What are 3 examples of physical change?
Physical changes are transformations that do not alter the chemical composition of a substance. Instead, they involve a change in the form, shape, or state of matter. Here are three common examples of physical changes:
1. Melting Ice
When ice melts, it changes from a solid state to a liquid state. This process is a physical change because the chemical composition of water remains the same; it is simply transitioning from a solid to a liquid. Melting ice is a common example of a physical change that occurs in everyday life.
2. Cutting Paper
Cutting paper is another example of a physical change. When you cut paper, you are altering its shape and size, but the chemical composition of the paper remains unchanged. The paper still consists of the same fibers and materials, but its physical appearance has been modified.
3. Boiling Water
Boiling water is a physical change that involves a transition from a liquid state to a gaseous state. When water reaches its boiling point, it turns into steam, which is a gas. This process does not alter the chemical composition of water; it merely changes the state of matter. Boiling water is a fundamental example of a physical change that occurs in many household and industrial applications.
