I am doing a lab design. i need some useful information about How can the temperature of ruler affect the strength of electricity hold of the paper? First i rubbed the rulers with different temperatures,then i try to use the rulers to attract paper pieces to see difference of quantities of paper pieces in different conditions. But actually i need some research about the background and those relevant scientific explanation.Thank you so much!

Expert Answer

Step 1

When you rub the ruler against an object, say a woolen cloth, the electrons in the outermost shells of the woolen cloth reaches the ruler and the ruler is excess of electrons.

Step 2

If the temperature of the ruler is higher, then more electrons reaches the ruler. This is because the numb...
