Question

When testing the freezing point of water, why is it that

youshould keep the thermometer from touching the bottom or the
sidesof the beaker.

Answer 1

Step-by-step explanation:

It's important to not touch the sides of the test tube with the thermometer to ensure the temperature is being measured of the solution, not the glass.

This is to avoid fluctuations in actual reading of the solution in the test tube & to measure the correct temperature of the solution, because the sides and bottom of the test tube will likely be at significantly different temperature than the solution in the test tube
