Why was it important not to let the thermometer rest on the bottom of the breaker?
to get an accurate reading of the liquid inside the beaker, the thermometer should not rest on the bottom of the beaker.
Why should the thermometer be kept from touching the sides and bottom of the beaker?
if the thermometer touches the buttom or the side of the be aker you will get the temperture of the beaker and not the boiling water
To ensure that the heat from a burner is spread evenly across the bottom of a beaker, one should use a _______.?

Why should the thermometer not touch the sides of beaker?
The bottom is hotter. When you are heating a beaker on a hot plate or even on a stove, the very bottom of the beaker is much hotter than the rest of the solution, especially if the solution is not very well stirred. The heat moves from the hot plate, through the bottom of the beaker and into the solution. Then the heat is transferred throughout the solution, but not instantly. So the heat is not distributed perfectly evenly throughout -- the top and sides of the container will be slightly cooler than the bottom. If the solution is stirred very strongly, the temperature won't be so uneven, but no matter water, the bottom of the beaker will be somewhat hotter than the rest of the solution. If the thermometer is touching the bottom of the beaker, it will read a hotter temperature than is real temperature of the solution.

What should students do if a beaker is cracked?
they should immediatly tell the teacher and listen to her instructions

Where should a beaker be placed with respect to the flame for the most efficient heating on Bunsen burner?
The most efficient, and safe, place for a beaker to be heated is above the flame. Have the beaker held up by the proper metal stand and have it held so that the flame is grazing the bottom of the beaker. Be careful though, the flame should only graze the bottom of the beaker so that the chemical doesn't heat up too quickly.
What should the students do to test these hypotheses?
perform an experiment that attempts to identify the gas above the open beaker
What should you do if you are supposed to boil water but the beaker has a creak in the bottom?
tell your teacher that the beaker is cracked because your teacher would probably know what to do and if you throw it away you might get in trouble.

Where should a thermometer be placed in a beaker?
The thermometer should be fully in contact with the solution in the beaker, and can not be in contact with the beaker, otherwise it will affect the temperature of readings.
