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.

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 when you bleach white cloth?
Bleaching white cloth removes stains and brightens the fabric by breaking down the chemical bonds that cause discoloration. The bleaching agent, typically hydrogen peroxide or sodium hypochlorite, oxidizes the color compounds in the cloth, leaving it whiter. It is important to follow instructions carefully to prevent damage to the fabric.
Is tearing cloth a physical or chemical change?
It is PHYSICAL CHANGE because it does not change into another substance and it does not have chemical reaction, it can be sewn back to return to its original form.
What happens when a polythene strip is rubbed on a woolen cloth and then placed near a thin stream of running water from a tap?
The polythene becomes negatively charged.

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 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 materials cause anaphylactic reactions?
cloth bacteria
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.
Is a dark cloth faded by sunlight a physical change?
Yes, a dark cloth faded by sunlight is a physical change. This is because the structure of the cloth has not been altered, only its color has changed due to exposure to light.
