TOWEL BY OUNCES OVER 8 SEPARATE EVENTS.

I subscribe to the theory that rinsing dishes in hot water allows them to air dry faster but my
husband stands by his estimation that it does not matter. He surmises that 1)the water cools
so quickly as to not give the initial heat any weight in evaporation, 2) Indoor drying makes it
even less possible for the hot water to make an impact on drying time. I decided to test the 2 opinions.

For each test, the same 4 plates were washed, put in the same drainer with the same space
between them. The room air and humidity were very similar each time as was the time of day.

My measurement ended up being weighing the paper towel used to wipe the dishes
after 10 minutes had elapsed.

  • The water is tepid, estimated to be about 80 Degrees with the faucet in the
exact same position each time

I submit that the influences on the date are not such that the data does not uphold my
opinion that hot water .
