Is a wrecking ball destroying a building a chemical change or physical?
The destruction of a building by a wrecking ball is considered a physical change. This is because the wrecking ball's impact causes a change in the building's physical state without altering its chemical composition.
Is a rolling a ball of clay into a long strand a chemical change?
No, rolling a ball of clay into a long strand is a physical change, not a chemical change. The clay's composition remains the same; only its shape is altered.
If before a basketball game the ref uses an air pump to inflate the basketball is it a chemical or physical change?
Inflating a basketball with an air pump is a physical change because it does not involve any change in the chemical composition of the materials involved. The air is simply being forced into the ball, causing it to expand and increase in volume, but the fundamental chemical makeup of the ball remains the same.
Changing water to ice is an example of a chemical change true or false?
I'd say no. Melting just changes the physical properties. Example: A rubber ball. If you melt a rubber ball it will still be rubber, just in a different form.
Is the volume of a soccer ball a chemical property?
No, the volume of a soccer ball is a physical property, not a chemical property. Chemical properties describe how a substance interacts with other substances in chemical reactions, while physical properties are characteristics that can be observed without changing the substance's chemical composition.
Is bouncing a ball a chemical change?
yes No. Nothing changes in its chemical nature.

If you crumple a piece of paper into a ball is the change physical or chemical?
it is a physical change

What is the physical change of making foil into a ball?
The physical change of making foil into a ball involves shaping and compressing the foil. By rolling and compacting the foil into a ball shape, its appearance and form are altered without changing its chemical composition.
Changing water to ice is an example of a chemical change true or false?
I'd say no. Melting just changes the physical properties. Example: A rubber ball. If you melt a rubber ball it will still be rubber, just in a different form.
What are the physical change of a tennis ball?
A physical change in a tennis ball could be flattening or deformation from being hit or squeezed. Another physical change could be discoloration or fading of the ball's outer fabric due to exposure to sunlight or wear and tear.
What is phiscal change?
Physical change is a concept introduced to contrast with the concept of chemical change. A physical change is any change not involving a change in the substance's chemical identity. Matter undergoes chemical change when the composition of the substances changes: one or more substances combine or break up (as in a relationship) to form new substances. Physical changes occur when objects undergo a change that does not change their chemical nature. A physical change involves a change in physical properties. Physical properties can be observed without changing the type of matter. Examples of physical properties include: texture, shape, size, color, odor, volume, mass, weight, and density. An example of a physical change occurs when making a baseball bat. Wood is carefully crafted into a shape which will allow a batter to best apply force on the ball. Even though the wood has changed shape and therefore physical properties, the chemical nature of the wood has not been altered. The bat and the original piece of wood are still the same chemical substance. Changes are sometimes hard to categorize strictly as physical or as chemical. Dissolving a salt in water involves the breaking of chemical bonds, yet is often described as a physical change. Some teachers hold that a chemical change is a rearrangement of atoms, but many physical changes also involve the rearrangement of atoms. Many chemical changes are irreversible, and many physical changes are reversible, but reversibility is not a certain criterion for classification. Although chemical changes are often recognized by an indication such as odor, color change, production of a precipitate, or production of a gas, every one of these indicators can result from physical change.
Is the volume of a soccer ball a chemical property?
No, the volume of a soccer ball is a physical property, not a chemical property. Chemical properties describe how a substance interacts with other substances in chemical reactions, while physical properties are characteristics that can be observed without changing the substance's chemical composition.
A sheet of paper is torn in half Another sheet is burned A third sheet of paper is crumpled into a ball What kind of change has each sheet of paper undergone?
Well, isn't that interesting! The first sheet of paper underwent a physical change when it was torn in half. The second sheet experienced a chemical change when it was burned. And the third sheet went through a physical change when it was crumpled into a ball. Each sheet transformed in its own unique way, just like how every brushstroke creates a beautiful painting.
Why is evaporation of mothballs a physical change?
That is a physical change because the evaporated moth ball chemical is still the moth ball chemical, just in a different form. It's similar to water . . . water is water no matter if it is solid, liquid, or evaporates to a gas.
