An ice cube melting into water and then refreezing back into an ice cube is an example of reversible change. Another example is heating and cooling certain metals, such as a paperclip, which can be straightened when heated and then reshaped when cooled.
Soft objects have a low rigidity and can easily change shape when pressure is applied, while hard objects have high rigidity and maintain their shape under pressure. Soft objects often have a smooth surface texture, while hard objects are typically rough or firm to the touch. Examples of soft objects include pillows or sponge, while examples of hard objects include rocks or metal.
Examples of everyday forces include pushing a door open, lifting a bag of groceries, driving a car, and throwing a ball. These activities involve the application of force to move objects or change their speed or direction.
Examples of forces at work include gravity pulling objects toward the Earth, tension in a stretched rubber band, a person pushing a box across the floor, and the magnetic force between two magnets. These forces can cause objects to move or change shape.
When a ball moving hits a ball that is at rest and a human pulling out a book from a desk.
Push, gravity, and friction are all examples of forces that can cause objects to move or change their motion. Push and gravity are forces that can cause objects to accelerate, while friction is a force that opposes motion and can cause objects to slow down. They all involve interactions between objects and the forces acting on them.
no....it is a physical change as it is only changing its state and it is reversable. somtimes it is reversable
irreversible change.
physical change are reversable
yes. a chemical change/reaction is irriversable, whereas a physical change/reaction is reversable.
During freezing the chemical nature of mercury remain unchanged.
No, dissolving a sugar cube in water is a physical change, not a chemical change. The sugar molecules simply disperse in the water, breaking apart but not undergoing a chemical reaction to form new substances.
physical change is reversable while chemicle change is not and they both change because of some kind of energy that's all i can think of srry.
Objects such as wool blankets and skills such as horsemanship among plains Indian Tribes are examples of the Colombian exchange causing cultural changes.Cultural Changecultural change
An example of a household endothermic reaction is boiling water. The process of water going from the liquid to gas phase is an endothermic process (you have to put heat into the water).An example of a household exothermic reaction is the burning of natural gas occurring on a stove-top or in an oven to cook food. The natural gas, mostly methane, CH4, burns by combining with oxygen to from carbon dioxide and water (and some other by-products such as carbon monoxide). This exothermic reaction creates the heat to cook with. Another example is burning wood or coal.An example of a substance in the liquid phase is water! Some other common examples of liquids are oil, gasoline, rubbing alcohol, and acetone (nail polish remover).
change in the form -in general can be indicated for the physical form. The substance may dissolve or its stage may change. If the change is physical, it should be reversable.
Gravity Electro-magnetic force Direct impact or contact
The change in an objects position is called motion.
