Is deflating a basketball physical change?

Is deflating a basketball physical change?

Q. Which best describes why deflating the air from a basketball is an example of a physical change? The basketball’s shape is changed. The basketball’s mass does not change.

Is deflating a physical change?

Physical change is a change in which only the physical properties such as size, shape etc change and there is no rearrangement of atoms. 1. Deflating a rubber balloon only decreases the size of balloon and hence is a physical change.

Is inflating a ball a physical change?

Inflating a balloon is a physical changebecause all it’s doing is adding air to the inside of the balloon, nochange in substance is occurring.

Why is bending a physical change?

All physical changes can include smashing, hitting, cutting, bending, sharpening. All of these methods are physical changed because even though they could be getting hit or smashed, the chemical structure remains untouched. It is also known as a physical change because it is not forming a new substance.

Is baking a cake a chemical change?

When you bake a cake, the ingredients go through a chemical change. A chemical change occurs when the molecules that compose two or more substances are rearranged to form a new substance! When you start baking, you have a mixture of ingredients. After you make your batter, you bake it in an oven and out pops a cake!

Is freezing alcohol a chemical or physical change?

Freezing point is a physical property as the change is physical that is from liquid it changes to solid state but chemical properties remains unchanged …so a physical change takes place and so it is a physical property.

Is frying eggs a chemical change?

When chemical bonds are broken or formed, new particles are created. Therefore, frying an egg is a chemical change because it results in the formation of new particles.

Is cooking oatmeal a chemical change?

The change is physical. Physical Change- Pouring milk on oatmeal does not change the chemical composition of the oatmeal; no chemical reactions takes place when these two ingredients are mixed. Chemical Change- When something burns, it undergoes the process of combustion.

Is baking powder mixed with water a physical or chemical change?

Explain that two of these three substances in baking powder are the “active ingredients” that react to produce bubbles when water is added. When the two active ingredients are combined with water, a chemical reaction occurs and a gas is produced.

What are the evidence of physical change?

Common physical changes include melting, change of size, volume, color, density, and crystal form. The classic baking soda and vinegar reaction provides evidence of a chemical change due to the formation of a gas and a temperature change.

What are 10 examples of physical changes?

Examples of Physical Changes

• Crushing a can.
• Melting an ice cube.
• Boiling water.
• Mixing sand and water.
• Breaking a glass.
• Dissolving sugar and water.
• Shredding paper.
• Chopping wood.

Is bending a spoon physical change?

The spoon can be bent. It is a physical change because it does not change the composition or properties of the particles that make up the spoon. There might be some changes in the temperature, but it does not cause a chemical reaction and it does not change the identity of the spoon.

What happens to a basketball if it is not inflated?

If a ball is not inflated fully, it will bounce low and erratically. On the other hand, excessively over-inflating a ball might break the bladder and cause leaks, negatively impacting the consistency of the ball’s bounce.

How does air affect the shape of a basketball?

As the molecules move about, they come in contact with surfaces of objects. The molecules push and press on those surfaces, exerting pressure on them. It’s that pressure that allows your basketball to keep its round shape and remain hard and bouncy. If air escapes from the ball, the pressure inside the ball changes.

Why does a deflated football have less mass than a fully inflated ball?

A quick calculation shows that the difference in mass between a fully inflated ball and a slightly deflated one is fairly small, Michael Eads, an assistant professor of physics at Northern Illinois University, said in a statement emailed to Live Science. A deflated football has a smaller mass because it has fewer gas molecules inside of it.

What happens to the volume of a basketball when it bounces?

If you have an empty basketball it will be “scrambled”. If we pump it up, the surface area will not change, but the volume will increase. If we keep going, both the volume and the surface area will not change significantly, because they are correlated. However, the basketball will explodes eventually.
