Question

What was the temperature of the flasks of glucose, fructose, maltose, and maltotriose, respectively, at the end of the reactions? as measurements will vary slightly, pick the answer that is closest to yours?

Answer 1

295.4 K, 295.3 K, 294.9 K, and 294.7 K

Step-by-step explanation:

In lab work, it is critical to check for the correct units of measurement. This lab uses a Kelvin scale for temperature, so you can quickly rule out the answer choice that uses Celsius. Ensure that you re-set the thermometer to Kelvin before adding each new sugar solution to the flask. It is also important to check that numerical values are logical. The answer choice that has values ranging from 22.5 K to 26.8 K does not make logical sense. For example, 25.7 K is equivalent to -247.5 C, which is far too cold for yeast to undergo anaerobic respiration! Deciding between the two answer choices that use Kelvin and make logical sense requires precision when performing the simulation and recording the final values. When the steps are performed correctly, the temperature of the solutions after the reactions will be:

Glucose - 295.4 K

Fructose - 295.3 K

Maltose - 294.9 K

Maltotriose - 294.7 K
