Are alcohol thermometers better than mercury thermometers?
They both have advantages and disadvantages: A mercury-in-glass thermometer can measure high temperature (up to 357 0C, the boiling point of mercury; and its freezing point is -39 0C). An alcohol-in-glass thermometer can measure low temperature (down to -115 0C, the freezing point of alcohol; and its boiling point is 78 0C.) A mercury-in-glass thermometer can quickly response to temperature, while an alcohol-in-glass thermometer can only slowly response to temperature. However, mercury is poisonous and alcohol is NOT poisonous. Also mercury thermometers are not allowed on aircraft.
Can a clinical thermometer be used to measure the temperature of boiling milk?
I know not of the answer to this particular question?
What to use to measure the temperature of boiling water?
I usually use a cheese thermometer. They are very accurate.
How do you use boiling point in a sentence?
The boiling point is the temperature at which a substance boils. Different substances have different boiling points. The boiling point of water is 100 degrees Celsius. You have to have an accurate thermometer to measure boiling point.
What is the use of thermometer in distillation?
1. The thermometer in the still head measures the boiling point of the liquid in the distillate. We can be sure of this because the boiling point of the boiling flask will vary based on how many compounds are in it. The thermometer measures the temperature of the vapor at the top of the column; this vapor will be cooled through the condenser and will condensate in the graduated cylinder at the product end of the apparatus. Therefore we are measuring the boiling point of the distillate vapor that is being condensed and collected.
Why can't and alcohol thermometer be used to measure the boiling point of water?
Because the boiling point of alcohol is lower than the boiling point of water.
What is the safe way to check the temperature of boiling water?
With a thermometer
Can we use a clinical thermometer to measure the temperature of boiling water?
No.

What is the range of alcohol thermometer?
The alcohol thermometer is used to measure temperatures from negative 115 degrees Celsius to 785 degrees Celsius. It measures the freezing point and boiling point of alcohol.
What type of common instrument that has temperature of ice and boiling water?
thermometer
Liquid alcohol will change to vapor when its temperature reaches the what?
Liquid alcohol will change to vapor when its temperature reaches its boiling temperature. When alcohol reaches its boiling temperature, each molecule of alcohol has enough energy to separate from each other, so each molecule can move freely. The boiling point of liquid alcohol is 351K or 78C
What thermometer is based on the metric system?
That depends on what units the thermometer is calibrated in. The SI unit for temperature is the kelvin, but degrees Celsius commonly used, if the thermometer reads in kelvin or degrees Celsius then it is a metric tool.
Uses of alcohol thermometer?
An alcohol thermometer is a liquid-in-glass thermometer which uses ethyl alcohol to gauge temperatures. The alcohol rises and falls as it contracts or expands when a change in temperature occurs.
How a thermometer helps you compare the energies of particales?
A thermometer doesn't actually measure the heat ENERGY in the molecules, instead it just compares the HOTNESS and COLDNESS with the melting and boiling point of water or any two other important temperatures. Heat energy is measured in joules and temperature is measured inCelsius,Fahrenheit, or kelvin.
Why is the thermometer not suitable to measure the freezing point and boiling point of water?
Although a thermometer CAN be used its presence affects the temperature.
How did Celsius come about?
Celsius was invented as a way of measuring temperature. A scientist named Anders Celsius put a thermometer in water until it froze, and marked where the mercury level was. He then measured the level in boiling water. The temperature in boiling water was given 100 Celsius, freezing was given 0 Celsius.
