Why should the bulb of the thermometer not touch the sides and bottom of the container when the temperature of the substance in it is to be taken?

The container may not be the same temperature as the solution (especially if the container is not a very good heat conductor). Thus, having the bulb of the thermometer touch the container may give an inaccurate reading.

Why should a thermometer not touch the sides of the test tube and should be placed in the middle?
If you place the thermometer so it touches the sides of the test tube, you are measuring the temperature of the test tube, not the substance in the test tube. So, in order to get an accurate reading of the substance, do not touch the sides of the test tube with the thermometer.
When syrup is pored in water it will go to the bottom of the container because?
Syrup and water do not mix so the syrup drops directly down to the bottom because it is a heavier, and thicker substance than water, so therefore will sink to the bottom of the container.
Why sugar settles down at the bottom of the container when you place concentrated sugar syrup in the refrigerator?
As the temperature of the solution decreases, less sugar can be held in solution, so some of it goes out of solution and falls to the bottom of the container.
What is thermometer clamp?
The clamp holds the thermometer up right at the right hight. the bottom of the thermometer shouldn't be touching the bottom of the beaker or what ever it is. make sure the clamp his holding the very top of the thermometer so you can see the numbers.
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.

What is a preciitate?
A precipitate refers to a solid substance that is deposited at the bottom of a container from a solution.
What happens to the mercury in the thermometer when the air is cool?
In a mercury thermometer, the level of mercury falls as the temperature of the air around it cools.A mercury thermometer has a bulb of mercury at the bottom and a thin tube above it with markings in Celsius degrees or Fahrenheit degrees. When the temperature warms, the mercury expands and rises up the tube. When the temperature cools, the mercury contracts and shrinks back toward the bulb at the bottom.

Syrup and water do not mix so the syrup drops directly down to the bottom because it is a heavier, and thicker substance than water, so therefore will sink to the bottom of the container.
What kind of thermometer is used for oral?
An oral thermometer is used for in the mouth and usually under the tongue. A rectal thermometer is used for taking your temperature from your rectum/bottom. They will be label in your grocery store or pharmacy whether there intended for your mouth or rectum.
Why is it important to have the bulb of a thermometer submerged in liquid without touching the sides or bottom of the beaker?
The sides or bottom of the beaker will likely be at a significantly different temperature than the liquid.
Why does mercury go up or down in a thermometer?
The mercury in the bulb at the bottom of the thermometer expands or contracts depending on the amount of heat (the temperature). The narrow calibrated tube that you read the temperature on acts to amplify this effect. The calibration is usually either in Fahrenheit or Celsius.
Why sugar settles down at the bottom of the container when you place concentrated sugar syrup in the refrigerator?
As the temperature of the solution decreases, less sugar can be held in solution, so some of it goes out of solution and falls to the bottom of the container.
What instrument measures changes in temperature?
Temperatures are measured by instruments called thermometers.The instrument usually used to measure air temperature is the maximum-minimum thermometer. It consists of a U shaped tube with bulbs at each end and mercury at the bottom. Air heats or cools the bulbs causing the air inside to expand or contract, therefore pushing or pulling the mercury upwards or downwards.There are 3 types of thermometer: minimum thermometer, maximum thermometer,and the "Six's thermometer" -- these record the temperatures over a period of time.it says in my book that a thermometer measures air temperature
