Paragraph describing the difference between physical and chemical changes. (must be a minimum of 5 sentences)

Please answer this quickly! I need it in the next few hours.

I can help you give me 10 minutes to write something out

Physical changes make a physical change, Chemical changes make a chemical change. Physical changes are temporary; however, chemical changes are more permanent. A physical change absorbs little to no energy and a chemical change absorbs energy. Lastly, a physical change can change the sizes shape, size, etc. However, a chemical change changes both physical and chemical properties. Some examples of physical changes are freezing water, boiling water, and melting wax. Some examples of chemical changes are the digestion of food, rusting, burning of coal, etc.

Hope this helps!!

wrote better than me 😭

lol I try

A physical change refers to a transformation in the appearance or state of matter without changing its chemical composition. This means that the substance involved retains its molecular structure and properties throughout the process. Physical changes are usually reversible, meaning the original substance can be restored. Examples of physical changes include freezing water to form ice, melting ice to water, and dissolving sugar in water. On the other hand, a chemical change involves rearranging the atoms or molecules of a substance, resulting in the formation of new substances with different chemical properties. Chemical changes are often irreversible and accompanied by the release or absorption of energy. Examples of chemical changes include burning wood to produce ash and smoke, baking a cake to form a new mixture, and rusting of iron. It is important to note that identifying physical and chemical changes often requires observation, experimentation, and understanding of the properties of matter.

Did you know?

Did you know that there are two main types of changes that can occur in matter? Physical changes involve altering the appearance or form of a substance without changing its chemical composition. For example, melting an ice cube to obtain liquid water is a physical change since it is still composed of the same H2O molecules. On the other hand, chemical changes occur when substances combine or break down to form new substances with different properties. In these changes, the chemical composition of the substances is altered. An example of a chemical change is when hydrogen gas reacts with oxygen gas to form water. Understanding the difference between physical and chemical changes is crucial in fields like chemistry and physics, as it helps scientists explain and predict the behavior of matter.
