Question

question 1. laundry in a clothes dryer often becomes charged with static electricity while drying. which best explains why clothes dry a. short - circuits in the dryer charge the laundry. b. heat from the dryer charges the air and produces sparks. c. clothes with metal pieces conduct electricity in the dryer. d. electrons are transferred as clothes rub against each other in the dryer.

Explanation:

Static electricity in clothes dryers is caused by the triboelectric effect. When clothes rub against each other, electrons are transferred between them. Option A is incorrect as short - circuits don't charge laundry in this context. Option B is wrong because heat from the dryer doesn't charge the air to produce sparks in this way related to static on clothes. Option C is not the main cause as metal pieces conducting electricity is not the root cause of general static on clothes. Option D is correct as electron transfer due to rubbing is the main mechanism for static electricity build - up in the dryer.

Answer:

D. Electrons are transferred as clothes rub against each other in the dryer.
