Answers & Comments
Answer:
Washing machines don't have hot air in them for drying clothes.
Explanation:
they spin the clothes strongly in the machine and a force called centrifugal force acts on the clothes and squeezes the water out from the clothes.
This process is called centrifugation.
Seemas teacher seems to be an expert in this field of chemistry.
