What does physical and chemical mean in science?
Chemical change: the composition of the initial reactants is changed. Ex.: thermal decomposition of calcium carbonate. Physical change: the composition is not changed during this transformation. Ex.: boiling of water.
Volume of a paper clip?
Think of a paper clip as a cylinder that has been bent into a specific shape. Determine the volume of the cylinder, and you have the volume of the paper clip. So, the area of the end of the cylinder x length of the cylinder = volume of the paper clip.
How come you can lift a paper clip with a magnet without touching it?
magnet attracts iron. paper clip made of iron magnet atrracts paper clip...
Measurements for a stretched out paper clip?
An regular size paper clip streaches out to four and a half inches.
Explain how you would find the volume of an object such as a paper clip?
The easiest way to find the volume of irregular objects is to use water displacement Fill a beaker or other container with water and place the paper clip in the water. The amount the water level rises is the volume of the paper clip. Of course because a paper clip is so small you would either need to use highly accurate measuring devices or place enough paperclips in the water that there is a noticeable change in water level. you would then divide the change in water level by the number of paperclips you put in to get the average volume of a single paper clip.
Is a paper clip is a chemicals change?
no
Is a paper clip bending a chemical or physical change?
Bending a paper clip is a physical change because the composition and structure of the paper clip remain the same. No new substances are formed during this process.
Is melting paper clip a physical or chemical change?
Melting a paper clip is a physical change because it does not alter the chemical composition of the paper clip. The paper clip simply changes from a solid state to a liquid state and can be reversed by cooling it back to a solid.
Is picking up a paper clip with a magnet a physical change?
No, picking up a paper clip with a magnet is not a physical change. It is a demonstration of magnetic force and involves no permanent alteration to the paper clip's structure or composition.
Example of physical change shape?
bend a paper clip
Is bending a paper clip a chemical change?
No, bending a paper clip is a physical change because the material of the paper clip remains the same before and after bending. Chemical changes involve a change in the chemical composition of a substance.
Is magnetizing a paper clip considered physical or chemical change?
Magnetizing a paper clip is considered a physical change. This is because the process of magnetization does not alter the chemical composition of the paper clip. The magnetic properties are induced by aligning the magnetic domains within the material, which is a reversible process. Chemical changes, on the other hand, involve the formation of new substances with different chemical properties.
Is picking up a paper clip with a magnet a physical or chemical change?
Picking up a paper clip with a magnet is a physical change because no new substances are being created. The paper clip's position is simply being altered by the magnetic force.
What happen in paper clip when bend?
When a paper clip is bent, the metal experiences stress, which can lead to deformation. Initially, the paper clip may return to its original shape if the bending is within its elastic limit. However, if it is bent beyond this limit, it will undergo plastic deformation, resulting in a permanent change in shape. Repeated bending can eventually lead to metal fatigue, causing the paper clip to break.
Is a rusting paper clip a physical or chemical change?
Rusting of a paper clip is a chemical change. It involves the iron in the paper clip reacting with oxygen in the air to form iron oxide (rust). This change is not reversible and results in a new substance with different properties.
What are some properties of a paper clip?
it is shiny it is sharp it is bent
How and why was the paper clip was invented?
The first patent for a bent wire paper clip was awarded in the United States to Samuel B. Fay
