Why did they use brandy in thermometers?

Unlike the mercury-in-glass thermometer, the contents of an alcohol thermometer are less toxic and will evaporate quickly. The ethanol version is the most widely used due to the low cost and relatively low hazard posed by the liquid in case of breakage.

How did they measure temperature in the 1600s?

1600s. 1624 — The word thermometer (in its French form) first appeared in La Récréation Mathématique by Jean Leurechon, who describes one with a scale of 8 degrees. 1638 — Robert Fludd the first thermoscope showing a scale and thus constituting a thermometer.

Why is alcohol used in thermometers instead of mercury?

Mercury has a greater coefficient of thermal expansion than alcohol. This means a column of mercury will expand and rise more than a column of alcohol for the same temperature change. As a result, you can get finer readings with mercury.

How accurate are old mercury thermometers?

They state: “The most accurate thermometers were within 0.5 degree of our medical thermometer, and all but one were at least good at repeating a retaken temperature. If you are looking for a way to get rid of that old standard thermometer, the EPA suggests giving it to your primary doctor since mercury is toxic.

Why is mercury used in thermometers?

Mercury is the only one in liquid state at room temperature. It’s used in thermometers because it has high coefficient of expansion. Hence, the slightest change in temperature is notable when it’s used in a thermometer. It also has a high boiling point which makes it very suitable to measure higher temperatures.

What are various method of measuring temperature?

The seven basic types of temperature measurement sensors or temperature checking devices discussed here are thermocouples, resistive temperature devices (RTDs, thermistors), infrared radiators, bimetallic devices, liquid expansion devices, molecular change-of-state and silicon diodes.

How did people measure temperature when there was no thermometer?

One used freezing and boiling points of water, another used freezing points of salt water and pure water, and still another made a scale where 0 degrees was ice melting and 12 degrees was human body temperature!

What is alcohol thermometer and what is the advantage of using alcohol thermometer?

A thermometer comparison

Are mercury thermometers more accurate than alcohol?

It is more durable than alcohol thermometer because mercury does not evaporate easily. It is smaller in size as compared to alcohol one. Mercury does not wet the wall of the thermometer, which means that results can be highly accurate.

Did you know Brandy was used instead of mercury in thermometers?

In The 1600’s, Brandy Was Used Instead Of Mercury In Thermometers. National Brandied Fruit Day is observed annually on October 20. Brandied fruit is fresh, sweet fruit that is soaked in brandy and sugar, which is then used as a topping on pies, cake or ice cream.

What was used instead of mercury in thermometers in the 1600s?

In The 1600’s, Brandy Was Used Instead Of Mercury In Thermometers

What was the first thermometer made out of?

Some of the earliest thermometers—used in the 1600s—contained brandy instead of mercury. The liquor was eventually replaced with mercury due to the latter material’s wider range of liquid-state temperature.

Why are thermometers filled with mercury instead of alcohol?

Because of alcohol’s high coefficient of expansion, mercury was chosen as a better candidate for filling thermometers. Mercury also has a high coefficient of expansion, but it is not too high. Mercury’s is about six times less that of alcohol.
