Answer:
The Einstein–Szilard or Einstein refrigerator is an absorption refrigerator which has no moving parts, operates at constant pressure, and requires only a heat source to operate. It was jointly invented in 1926 by Albert Einstein and his former student Leó Szilárd, who patented it in the U.S. on November 11, 1930.
Explanation:
Who Was Alexander Graham Bell?
Alexander Graham Bell was a Scottish-born scientist and inventor best known for inventing the first working telephone in 1876 and founding the Bell Telephone Company in 1877.
Bell’s success came through his experiments in sound and the furthering of his family’s interest in assisting the deaf with communication. Bell worked with Thomas Watson on the telephone, though his prodigious intellect would allow him to work on numerous other inventions, including flying machines and hydrofoils.
