Hey can someone please tell me what they would write for this question as a generic answerr?

Thanks :biggrin:

Because I momentarily ran out of space to store them on the shelves.

Only kidding, but seriously: you need to be more specific. What's the context? What do the tubes contain? What's the experiment?

So that they have time to reach the temperature of the water baths. If your test tubes had been at 10oC and then dipped them into a water bath of 90oC for only a second, that would not get the test tubes to the correct temperature.

The answer is probably to allow the contents to uniformly reach the desired temperature.

OR: To allow the contents of the tube to melt (if they are a solid)

OR: To ensure all the tubes start at the same temperature

OR (less likely): To kill any bacteria that can't take the heat

But as the previous poster says, we need context.
[Edit: I mean the poster two before me.]

The answer is so that the testubes and the water bath have the same temperature, i.e. equillibriate.

like why would you put a tollens reagent test in a water bath for 5 minutes and why are conditions such as temperature, time important?

Why is it important to heat tollen's reagent in a hot water bath for 5 minutes, and why are the conditions of temperature and time important for the reaction to occur?
