William writes the following description of how objects are attracted to each other. Charges transfer from one object to another. A charged object next to an uncharged object will repel each other. A positively charged object and a negatively charged object will attract each other.

What is the error in William's description?

A charged and uncharged object attract each other.
Charges are transferred from water to objects.
Transfer of charges occurs due to heat.
Two charged objects attract each other.
