both get charged but with charges of opposite nature
the rod slightly attract each other
The glass temperature transition is for glass, polymers, etc. (amorphous or semicrystalline materials), but not for leather.
on rubbing glass with silk, the former one becomes positively charged whereas the other negatively charged.
Amber has the ability to pull and store electrons from other elements and fabrics ,especially silk which when rubbed causes a static shock.Transferring electrons , In part due to the sub atomic make up of the amber, which consists of acidic based compounds which is believed to have formed from long extinct trees sap which are only closely associated to trees now living in New Zealand .
pure silk comes from silk fibers artificial silk comes from fibers that soft and "feel silky".
the silk will rub of the electrons on the silk, leaving the glass positively charged
when a glass rod is rubbed with silk cloth, some of the electrons are removed from the atoms of the glass rod and deposited on the silk leaving negatively carged and glass positively charged Different materials have different electron affinities, meaning electrons will tend to gravitate towards certain materials over others. When silk is rubbed against a glass rod, the atoms of the rod and the atoms of the silk interact, and the silk atoms pull electrons from the rod's atoms. Thus, the silk winds up negatively charged and the rod becomes positively charged. Source: http://www.physicsclassroom.com/class/estatics/u8l2a.cfm
When glass rod is rubbed with silk cloth it becomes positively charged and the silk cloth becomes negatively charged. This is because the glass rod looses electrons to the silk cloth which makes it positive and the silk cloth becomes negative.
Silk Cloth
The Physicist who said first that the charge on a glass rod rubbed with silk is positive was Michael Faraday.
it flies up to the glass
The silk picked up positive charges.
Both are examples of static electricity generation. The big difference is the way the electricity is generated.
For example as glass rob is rubbed with silk then glass becomes positively charged and silk negatively charged. This is mainly because of the transfer of electrons right from glass to silk. But in case of ebonite rod rubbed with fur electrons get transferred from fur to ebonite. So ebonite becomes negatively charged and fur positive charged Now in case of an atom or molecule one or more electrons get removed and so that atom or molecules become a positive ion. Same way as electron gets attached with a neutral atom then it becomes negative ion.
Yes, rubbing a silk cloth on glass cause electrons to move to the cloth. As a result, glass rod acquires positive charge and silk acquires negative charge.
Positive charge
There is a very big difference between the electrical charge of a balloon rubbed in a person's hair and a glass rod rubbed with silk. The charge from the balloon will just make it stick to objects. The charge from the glass rod will emit a very large electrical shock that might knock a person to the ground. This is because the glass rod is a better conductor of electricity than the balloon.
