If I'm going to transfer a piece of metal (a reasonable size) from a beaker of boiling water into a calorimeter, what should I use? Tweezers are too small...I can only think of a beaker clamp, but they are, after all, for beakers.
Crucible tongs or a test tube clamp depending upon the size of the metal piece.
Crucible tongs are made of metal; therefore, I would leave them in the boiling water long enough for them to reach a temperature at least close to that of boiling water. That way, the metal at boiling water T won't lose heat to the cooler tongs during the transfer.
