The density of the object is at least equal to, and possibly
greater than, the density of the liquid in the beaker.
It falls down. When it reaches a hard bottom it is likely to bounce whereas if it hits water it will sink.

The purpose is to measure liquids and to boil it on your burner because of the big flat bottom and so you can pour the liquid a little more accurately when trying to do like a small drop of something.

The mass of undissolved potassium nitrate is cca. 3 g.
It is important not to let the thermometer rest on the bottom of the beaker because the bottom can be heated unevenly leading to inaccurate temperature readings. Placing the thermometer in the liquid away from the bottom ensures a more accurate measurement of the liquid's temperature.
The sides or bottom of the beaker will likely be at a significantly different temperature than the liquid.
increases due to the increased weight of the liquid. This is because the liquid's weight creates a force that is spread out over the bottom of the beaker, leading to an increase in pressure.
The bottom and sides of the beaker will be hotter than the liquid inside.
Letting the sand settle at the bottom of the beaker helps separate it from the solution, reducing the risk of contaminating the solution with sand particles. This step allows for cleaner and more accurate transfer of the solution into another beaker for further processing or analysis.
Luminous flame produce deposit on the bottom of the beaker because when the beaker is near the flame, it limits the amount of oxygen for the methane, thus, the deposit (which is Carbon), is produced.

A beaker is a cylindrical container with a flat bottom and spout for easy pouring, while an Erlenmeyer flask has a conical shape with a narrow neck. Erlenmeyer flasks are more suitable for containing substances that require mixing or swirling due to their shape, while beakers are better for holding and heating liquids.
Hold it by the top or use a clamp. But make sure before you take the temperature you stir the liquid around in the beaker first and that you do not let it touch the bottom of the beaker as the glass will be hotter than your liquid.
The students should not use the beaker with the crack as it poses a risk of breaking further while pouring water, potentially causing injury. They should find a different beaker that is intact and safe to use for their experiment.
