Ii its freezing point is below 100C. What are the advantage of mercury over alcohol.

Difference Between Alcohol And Mercury Thermometers Definition Mode Of Action Advantages Disadvantages Differences

Oral infect advantage arm fever - Health and Wellness -Doctors illness diseases nutrition sleep stress diet hospitals medicine cancer heart disease.

Mercury thermometer advantage. Mercury thermometers are highly durable because Mercury does not evaporate easily. Mercury vapour is poisonous. Display is harder to read.

Can you use an old glass rectal mercury thermometer orally. Quick reaction to changes of temperatures because metal is a good heat conductor. It gives results quickly has a fast response time.

Mercury thermometers give accurate readings. It is smaller in size as compared to alcohol one. Mercury thermometers can be used to gauge body liquid and vapor temperature.

It expands linearly and less than alcohol and any other liquid. Hence the slightest change in temperature is notable when its used in a thermometer. Advantages of Mercury as a thermometric liquid.

Pros of general-purpose infrared thermometer. Advantages of clinical thermometers include-the small constriction that is built into the thermometer which traps the mercury so that the temperature can be read after the thermometer has been removed form the patient s body. They are gun-shaped and take measurements by using lasers to point at the surface.

The mercury-in-glass or mercury thermometer was invented by physicist Daniel Gabriel Fahrenheit in Amsterdam 1714. However at a slow pace. Alcohol thermometers are less durable because alcohol evaporates quickly.

It is more durable than alcohol thermometer because mercury does not evaporate easily. The volume of mercury in the tube is much less than the volume in the bulb. Mercury is used in thermometers because it has high coefficient of expansion.

When the hot temperature is absorbed by the mercury the mercury will expand and begin to rise to a point that indicates the temperature of the object. -It is a good conductor of heat and therefore the whole liquid reaches the temperature of the surroundings quickly. A Freezing point of alcohol is 1 1 7 C and hence can record very low temperature For example in Arctic and Antarctic regions temperature may fall below 8 0 C which cannot be measured by mercury thermometer because mercury freezes at 3 9 C b The expansion of alcohol per degree rise in temperature is much more around six times more.

Its advantage is that the temperature of a patient can be obtained within just one second. Cannot be used for thermograph. When the temperature changes the mercury expands and contracts the temperature can then be read on the scale.

Simply point the thermometer at a persons forehead and press the button for results. Ad Safely and accurately determine body temperature with this Infrared Digital Thermometer. Mercury is a potent neurotoxin with poisoning symptoms that include tremors emotional changes insomnia neuromuscular changes performance deficits on tests of cognitive function and.

The volume of mercury changes slightly with temperature. Cannot be used for thermograph. They can measure those objects that cannot be measured using direct contact.

Mercury does not wet the wall of the thermometer which means that results can be highly accurate. It expands linearly and less than alcohol and any other liquid. I know the bulb is shorter to prevent breakage in the rectum but this shouldnt be a Old mercury thermometers rectal vs.

When it comes to thermometers like most things you get what you pay for. The pros of this type are the same as the cons of probe thermometers. Does not work below -39 0C Hg freezing pount accurate.

Simply point the thermometer at a persons forehead and press the button for results. Alcohol also called spirit-filled thermometers are inexpensive but they also break very easily. A slight amount of mercury is placed into the base of the thermometer and as heat warms the base of the thermometer it increases the mercury level pushing it up a narrow tube so we can physically read the increase on the thermometer.

I Alcohol has greater value of temperature coefficient of expansion than mercury. In other words Mercury Thermometers are compact and easy to take with you. The thermometer in which we use mercury as a thermometric liquid is called mercury thermometer.

In a mercury thermometer a small glass cylinder is filled with mercury and a standardized temperature scale is marked on the tube. Display is harder to read. As far as affordable thermometers go the mercury thermometer is the most accurate and has several other advantages over alcohol-based thermometers.

Advantages of using alcohol over mercury as thermometric liquid are. Does not work below -39ºC Hg freezing pount accurate. The most immediate advantage gained by replacing Hg thermometers is residential and workplace safety.

The above types of thermometers are some of the most widely used in medical application. The small change in volume drives the narrow mercury column a. Advantages of alcohol over mercury.

The traditional mercury or alcohol thermometer is still the most popular as it is cheap easy to use and gives accurate readings. Thus alcohol thermometer is more sensitive than mercury thermometer and can be used to measure the temperature below 40C. Mercury Thermometer Alternatives.

Alcohol thermometer compared to a mercury thermometer lower freezing point -114 ºC less durable alcohol evaporates. Ad Safely and accurately determine body temperature with this Infrared Digital Thermometer. Advantages of mercury.

Mercury thermometers are used to measure temperatures from 37 to 356 C. Advantage of mercury as a thermometric liquid Mercury is a good conductor of heat It needs very little heat to expand. It is more durable than alcohol thermometer because mercury does not evaporate easily.

Advantages and Disadvantages of Mercury Thermometers Advantages It is a good conductor of heat and hence can measure even high temperatures. However when the temperature drops the position of the mercury remains in place. A mercury thermometer is a thermometer that uses mercury as a filler.

It consists of a bulb containing mercury attached to a glass tube of narrow diameter.
