Lin sends away for a hot-cold serving tray she has seen advertised. The tray is promised to keep hot dishes hot and cold dishes cold without electricity. Lin tries it out by placing a pan of hot beans on it. They stay hot throughout dinner. "It works," she tells her husband.Invent at least one plausible alternative explanation of the effect.

What will be an ideal response?


The beans stayed hot all by themselves-that is, they would have stayed hot even if they had been placed on a standard trivet.
