- Boiling Liquids. Boiling uses heat to change a liquid to a gas. This occurs when the liquid reaches the temperature at which the vapor pressure equals the pressure of the gas above the liquid.
- Clouding and Condensation. Clouding occurs when a substance condenses from a gaseous state to a liquid state. Of course, one example of this change is actual cloud formation where water vapor in the sky condenses into water droplets.
- Dissolution or Dissolving. Dissolution, or dissolving, is the process of a solid or liquid forming a solution in a solvent. Pouring sugar into a hot cup of coffee is an everyday example of dissolution.
- Freezing or Solidification. Freezing, or solidification, is the withdrawal of heat from a substance to change that substance from a liquid to a solid. The temperature must be below the substance's freezing point for the change to occur.
Aug 12, 2022 · Some types of physical changes include: Changes of state (changes from a solid to a liquid or a gas and vice versa). Separation of a mixture. Physical deformation (cutting, denting, stretching). Making solutions (special kinds of mixtures). As an ice cube melts, its shape changes as it acquires the ability to flow.
Oct 19, 2023 · What Is a Physical Change? In a physical change, the material involved in the change is structurally the same before and after the change. Types of some physical changes are texture, shape, temperature, and a change in the state of matter.
- Change of State
- Change of Texture
- Change of Color
- Change in Temperature
- Change in Shape

Change of state refers to melting, boiling, freezing, and condensation. Ice melts into water and changes its shape. During this process, the chemical formula of ice, H2O, remains unchanged. Hence, the melting of ice is an example of endothermic physical change, which is represented by the following equation: H2O (s) + heat ⇌ H2O (l) When water is h...
The change in texture is defined by the change in the appearance of the material’s surface. When a piece of rough wood is sanded, waxed, and polished, it will look very different from before.
Changing the color of a substance is a physical change as long as there is no chemical reaction involved. For example, when you paint the surface of a car, the paint does not chemically react with the surface.
Although the temperature change is not visible to the eyes, it is considered a physical change. For example, consider a cooking pan sitting idle in a cupboard. It does not undergo any change. We do not physically see any change until we heat the pan. When we touch the hot pan, we can feel the heat. Therefore, the temperature of the pan changes. Eve...
Change in shape is an indication of physical change. When we wash, dry, and iron clothes, we fold them before putting them back in the wardrobe. We are only changing the shape of our clothes.

Remember, the appearance of matter changes in a physical change, but its chemical identity remains the same. Crushing a can. Melting an ice cube. Boiling water. Mixing sand and water. Breaking a glass. Dissolving sugar and water. Shredding paper.

A physical change involves a change in physical properties. Examples of physical properties include melting , transition to a gas , change of strength, change of durability , changes to crystal form , textural change, shape , size, color , volume and density .
Physical and chemical processes can be classified by the changes occurring on the molecular level. In general, chemical processes involve changes in chemical bonds, while physical processes involve changes only in intermolecular forces.
