What happens if thermometer breaks in mouth?

The non-silver liquid-in-glass thermometers typically contain a colored alcohol. Contact with the skin or inside the mouth could cause minor irritation or a burning sensation that should go away quickly. If the liquid spills rinse off exposed areas with water.

What is the Mad Hatter disease?

Mad hatter disease is a form of chronic mercury poisoning. Depending on the level of exposure it can cause symptoms like vomiting skin rashes tremors twitching and excitability. The condition is called “mad hatter disease” because it commonly affected hat makers in the 18th to 20th centuries.

What is alcohol in glass thermometer?

Noun. 1. alcohol-in-glass thermometer – thermometer consisting of a glass capillary tube marked with degrees Celsius or Fahrenheit and containing alcohol which rises or falls as it expands or contracts with changes in temperature. alcohol thermometer. thermometer – measuring instrument for measuring temperature.

How does alcohol in glass thermometer work?

Alcohol thermometers work by enclosing a narrow capillary attached to a bulb of reserve fluid. As the temperature heats up the alcohol expands rising up the capillary. As the temperature goes down the fluid contracts dropping down the capillary.

Why are thermometers filled with alcohol?

Alcohol thermometers are used rather than mercury thermometers in very cold regions because alcohol has a lower freezing point than mercury. … If it freezes it won’t move in the tube so a liquid must be used that has a freezing point that’s lower than the temperature it’s measuring.

How do you read a Galileo liquid thermometer?

How to read a Galileo thermometer. To read the ambient temperature on a Galileo thermometer is very easy. What you have to do is simply look at the lowest ball that is floating while ignoring those tags that had sunk to the bottom of the container. It’s those balls that float or are neutrally buoyant that interest us.

What is a thermoscope used for?

A thermoscope is a device that shows changes in temperature. A typical design is a tube in which a liquid rises and falls as the temperature changes. The modern thermometer gradually evolved from it with the addition of a scale in the early 17th century and standardisation through the 17th and 18th centuries.

Why did Galileo invent the thermometer?

In 1593 Galileo Galilei invented a rudimentary water thermoscope which for the first time allowed temperature variations to be measured. … It was perhaps the first crude clinical thermometer as it was designed to be placed in a patient’s mouth for temperature taking.

How did santorio invent the thermometer?

Shortly after Galileo Italian scientists Santorio Santorio invented the first thermometer by adding a paper scale to the thermoscope. Now the exact change in temperature could be measured. In 1654 the Grand Duke of Tuscany Ferdinando II invented the sealed liquid in glass thermometer.

Is liquid mercury poisonous to touch?
