Each insulated beaker contains equal amounts of the same fluid. The starting temperature of beaker A was 100.0 degrees Celsius and the starting temperature of beaker B was 0 degrees Celsius. At 5 minutes, the temperature of Beaker A was 82 and the temperature of Beaker B was 18. Assuming no heat was lost, what is the best estimate for the temperature of each beaker at 10 minutes?


  1. Hello, welcome to Brainly!

    If we are to say that no heat was lost, we would have to write this down as a absolute function.

    Beaker A lost 18 degrees in the span of 5 minutes (100 – 82) and Beaker B gained 18 degrees in the span of 5 minutes.

    This is where the problem gets tricky, because we have no second value for the second line of the function, though I doubt this question is that complicated.

    Now, what we do is we subtract 18 degrees from Beaker A, again, since 10 – 5 minutes is 5 minutes. We then add 18 degrees to Beaker B.


    Beaker A: 64° (82 – 18)

    Beaker B: 36° (18 + 18)
