In the experiment, you heated a sample of metal in a water bath and quickly removed and dried the sample prior to inserting it into the cold water "system". Why did you need to dry the sample prior to placing it into the cold water "system" a. The extra water might react with the metal which would ruin the sample.

b. Any residual hot water would have added to the heat transferred from the metal to the cold water "system".

c. The wet metal would not transfer any heat thus causing inaccuracy in you measurements.

d. The metal would oxidize in the presence of water thus ruining the sample
