inaccurate reading

Because the temperature of the bottom of the beaker may adversely affect the accuracy of the reading if the temp of the surface that the beaker is sitting upon is different from the temp of the contents of the beaker.
The thermometer should normally be suspended with its bulb at the center of the contents of the beaker.

because the thermometer would be measuring the temperature of the bottom of the beaker. this would result in both an innacurate reading, and a lowered grade in chemistry :P. Here is a link to help clear it up I hope. It has like science lab pranks and accidents.

If it touches the bottom you might get the temperature for the beaker and not the liquid which you are attempting to measure.

Because you are measuring the temperature of what's in the beaker. The beaker will be hotter while a flame is applied.
