When a cloth rubs against a ruler, friction causes electrons to transfer between the two materials, leading to a buildup of static electricity. This transfer occurs because different materials have varying affinities for electrons, resulting in one object becoming positively charged and the other negatively charged. The change in charge alters the interactions between the atoms in both the cloth and the ruler, affecting their electrical properties and causing them to attract or repel each other.

What happens to the atoms in the cloth and ruler to cause this damage?
When a cloth and a ruler come into contact, friction generates heat, which can cause the atoms in both materials to vibrate more intensely. This increased molecular motion can lead to the breaking of bonds between atoms, resulting in wear or damage to the surface of the materials. Additionally, if the friction is strong enough, it can cause microscopic particles to be abraded from the surfaces, further contributing to the degradation of both the cloth and the ruler.
Is spilling of acid on a cloth a physical or chemical change?
It is a chemical change only if this acid react with the cloth.
Do dying a cloth is what example of physical or chemical change?
There is a bit of both. The processes of spinning and weaving are purely physical. Bleaching and dyeing are chemical.
What happens to ice when you cover it black cloth?
When you cover ice with a black cloth, the dark color absorbs more sunlight and heat compared to lighter colors. This can cause the ice to melt faster due to the increased temperature caused by the absorbed heat. Additionally, the cloth may insulate the ice somewhat, but the primary effect is the enhanced melting rate due to the absorption of light.
Is burning a cloth a chemical change?
Yes, burning a cloth is a chemical change. When cloth is burned, it reacts with oxygen in the air, resulting in combustion that produces new substances such as ash, carbon dioxide, and water vapor. This process alters the chemical composition of the material, making it irreversible. Therefore, it is classified as a chemical change.

What happens to the cloth on the Ka'bah?
Ka'aba Cloth is a matter of change annully and they keep the old as i know ,, its made of silk and dicorated by Gold
When a balloon is rubbed with a wool cloth it becomes negatively charged why?
When a balloon is rubbed with a wool cloth, the electrons from the atoms of the wool cloth enter the atoms of the balloon and thus, the number of electrons in the atoms of balloon becomes more than the number of protons. Hence, there is a net negative charge in the balloon, whereas in the wool cloth the number of electrons in its atoms become less than the number of protons, hence there is a net positive charge on the wool cloth.
What happens when ypu put a wet cloth on a chip pan fryer?
Putting a wet cloth on a chip pan fryer can be extremely dangerous. The water from the cloth can cause the hot oil to splatter violently, potentially leading to burns or a fire. Additionally, the sudden temperature change may increase the risk of the oil igniting. It's crucial to keep water away from hot oil to ensure safety in the kitchen.
What happens when you rub a copper rod with a cloth?
When you rub a copper rod with a cloth, electrons are transferred between the two materials due to friction. This can cause a buildup of static electricity on the rod, giving it a slight negative charge.
Is spilling of acid on a cloth a physical or chemical change?
It is a chemical change only if this acid react with the cloth.
When you rub a ruler with a cloth what happens to the cloth?
Rubbing a ruler with a cloth creates friction, which transfers some of the ruler's electrons to the cloth, giving the cloth a negative charge. This process is called triboelectrification.
Why tearing of cloth is a physical change?
Yes. A change in shape took place. The changing of shape does not change any chemical properties of the cloth.
What happens to ice cube when you cover it with black cloth?
It melts
Do dying a cloth is what example of physical or chemical change?
There is a bit of both. The processes of spinning and weaving are purely physical. Bleaching and dyeing are chemical.
When a balloon is rubbed with a wool cloth why does it become negatively charged?
When a balloon is rubbed with a wool cloth, electrons are transferred from the wool to the balloon, giving the balloon a surplus of electrons, making it negatively charged. Wool has a higher affinity for electrons compared to the balloon material, which results in the transfer of electrons and the creation of a negative charge on the balloon.
What materials cause anaphylactic reactions?
cloth bacteria
