Question

Now let's try some other combinations, like twice the volume of warm water to one volume of cool. Using the balance might assist you in getting the ratios correct. Make sure the combined volume doesn't overflow the styrofoam cup! Measure the temperatures and attempt to predict the combined mixture temperature. T_1 = ______ degree C T_2 = ______ degree C My guess is T_find ________ degree C Now combine the two samples and measure the final temperature. T_find = ______ degree C How did your prediction compare to the measured value? Discuss in the box below.

Explanation / Answer

Predicted temperature, Tpred = 650 C

Measured temperature of the mixture, Tmeas = 68.10 C

Now, for comparing these two value, we have to determine the percentage error in our predicted value.

The expression for the percentage error = [(Tmeas - Tpred) / Tmeas] x 100

In our case, the percentage error in our prediction -

= [(68.1 - 65) / 68.1] x 100 = 0.0455 x 100 = 4.55 %
