What are 5 physical changes that can occur to a substance?
Melting: The substance changes from a solid to a liquid as heat is applied. Freezing: The substance changes from a liquid to a solid as it loses heat. Evaporation: The substance changes from a liquid to a gas as it is heated. Condensation: The substance changes from a gas to a liquid as it cools. Sublimation: The substance changes directly from a solid to a gas without going through a liquid phase.
If the air temperature dropped by 5 degrees would you feel it?
Yes, a change of 5 degrees in air temperature would likely be noticeable and you may feel the difference, especially if it happens relatively quickly. Our skin is sensitive to temperature changes, so a drop of 5 degrees could be felt as a change in comfort level or even trigger physical responses like shivering.
What are the 5 physical properties of matter?
The five physical properties of matter are color, odor, density, melting point, and boiling point. These properties can be observed or measured without changing the chemical composition of the substance.
5 processes that are physical changes?
Boiling water: Water changing from a liquid to a gas. Melting ice: Ice changing from a solid to a liquid. Dissolving sugar in water: Sugar particles evenly dispersing in water. Cutting a piece of paper: Paper being physically separated into smaller pieces. Crushing a can: Can being flattened without changing its chemical composition.

What is the difference between physical changes and physical properties?
A physical property is any characteristic of a material that can be observed or/and measured without changing the identity.A physical change is the change in which the properties of a substance change but the identity always stays the same.
What are the characteristic of physical change?
Some common characteristics of physical changes are change in texture, change in shape, and change in state. There can also be a change in temperature and a change in color, but these are also common characteristics of chemical changes. A physical change does not change the composition of the original substance.
What is the differences between chemical and physical change?
A chemical change results in the formation of new substances with different properties, while a physical change alters the state or appearance of a substance without changing its chemical composition. Chemical changes involve the breaking and forming of chemical bonds, whereas physical changes involve changes in the physical state, such as melting, freezing, or evaporating.
What changes occur in both male and females during puberty for grade 5?
Puberty starts at the age of 11/12 for girls and 13 for boys. There are many physical changes mainly increase in gonad sizes, height and fertility.
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
What kind of changes are physical changes?
Anything that can be observed without a chemical reaction taking place. IE: Ice melting, Water Boiling, The coke bottle you left in your car freezing into a solid brick. There are only 5 physical states, the 3 main ones being: Solid, Liquid, and Gas. Any of these changes (solid to liquid, etc.) are examples of a physical change. Other examples are breaking your phone into little pieces and grating cheese onto your pasta.
