Atoms of arsenic (As) are often added to silicon (Si) in a process called doping to change the conductivity of the silicon. how does the addition of arsenic change the conductivity of silicon.

Frictional forces acting on an object are often converted into energy, which causes the temperature of the object to rise slightly.
