Should you use a laboratory thermometer for stirring and why?
It's best not to, as thermometers can be quite fragile. A glass rod is preferable. (That said, you can get so-called stirring rod thermometers, made to be more robust, but they tend not to be very accurate and are really only meant for lower grade chemistry.)
What are the Uses of Mercury glass thermometer?
To measure the amount of heat in an object. Not to be confused with alcohol thermometers, mercury thermometers are not manufactured for public use anymore.
Why are glass rods used in labs for stirring?
Glass does not readily react with most substances, so it is well-suited for use in chemistry labs.
Why should you use a glass stirring rod when pouring liquids?
often when performing experiments in chemistry you are using dangerous chemicals. the purpose of the glass stirring rod is to a) slowly pour in the liquids so that it will not splash on you or your lab partners and b) to ensure that your pour the right amount of liquid into the solution. i.e. titration. However the main reason for the stirring rod is just to ensure safety.
Why can't you use mercury thermometers?
You can and many people do.

What is use for stirring chemicals?
a glass stirring rod
How are mercury thermometers used today?
Mercury thermometers are rarely used, except in lab thermometers. For human use, they have been replaced by dyed alcohol glass thermometers, or electronic digital thermometers.
How do you use glass rods?
you use them for stirring substances in the lab. (usually liquids)

What is the difference between clinical thermometers and other mercury-in-glass thermometers?
Clinical thermometers are specifically designed for measuring human body temperature, while other mercury-in-glass thermometers can be used for various purposes such as measuring temperature in laboratories or industrial settings. Clinical thermometers typically have a narrower temperature range focused on human body temperature, while other thermometers may have a wider temperature range. Additionally, clinical thermometers are often designed with features like an easy-to-read scale and a flexible tip for comfort and safety during use.
What is the use of a liquid-in -glass thermometers?
1. has a high boiling point 2. good conductor of heat 3. does not wet glass does not vaporize easily 4. has a wide temperature range
What is a laboratory stirring rod and how do you use it?
The Stirring rod is a long rod made of glass, but sometimes plastic, used to stir liquids. The rod is typically as thick as a pencil and between 6 and 12 inches long.
Give one reason why it is safer to use a plastic strip thermometers?
Because if you use a glass thermometer, there is more chance of disease or micro organisms being spread.
What is in the laboratory thermometer?
There are many kinds of thermometer in use. Liquid in glass thermometers usually contain alcohol (dyed red or blue) or mercury (silvery coloured).
When do you use a thermometers?
When you need them.
