THE NEW INVENTION: THE MERCURY THERMOMETER
Physicist Daniel Gabriel Fahrenheit invents the Thermometer
A week ago the Polish engineer Daniel Gabriel Fahrenheit of German origin living in Amsterdam where he works as a glass blower. There he began to develop precision instruments such as water thermometers (1709) and where he currently created the Fahrenheit scale and with it the Mercury Thermometer. This is used to measure the temperatures of the selected material but it has mainly been invented to measure the ambient temperature and for medical uses. On his scale, he used as a reference a mixture of water and ammonium chloride salt in equal parts in which the freezing and boiling temperature was lower than that of water. The freezing value of that mixture was called 0F, his body temperature was 96F, and the freezing temperature of the water without salts was called 32F.
In the medicinal field it is used to measure body temperature, the thermometer must be grasped by the upper end and shaken with a quick movement of the wrist until reaching 95F and once reached it must be placed under the armpit and left to act for 3 minutes and then You could already check the body temperature you have.
And to measure the temperature of a place, all we have to do is place the thermometer in a safe place and leave it there and we would mark the temperature.
In turn, it is a dangerous invention because it is composed of mercury, which is toxic and can cause major health problems, even death.
Not bad, it's just that this article is a little short. Despite this, the video is quite good. Cheer up guys!

I think that this article is not bad at all. It has really surprised me that you've done two news, so I think it is a very good thing. Even though this one is a bit short, I value the fact of looking for information for two different topics. About the content, I think it is OK, as it explains very well the information without overexplaining. I've also liked the video, as well as it's quite important to watch it in a moment like this, in which thermometers will become very useful.

This second news is like the other but a little bit more simple, it doesn’t feel as intriguing and smooth, maybe some more links would have been nice to go with the news, but overall, it’s quite nice, specially the video chosen.
ReplyDeleteFinally, your news results so simple and it is evident you weren´t so interested on doing a good work. So that, your mark for this job is 5.
