Symptoms of the Black death

In Choas, we have been tasked to know info about the black death

Types of plague/3 strains of the black plague

1.  Bubonic: Causes a swollen/inflamed lymph nodes in the armpit and groin

2. Pneumonic: Affects the lungs.

3. Septicemic: is an infection within the bloodstream. 

Which century was the black death and what parts of the world did it impact?

Middle ages and Europe and Asia.

Who were the victims of the black death?

The black death target anyone it wasn't just a specific person.

How was the dead buried? 

They were buried in mass graves or thrown into a river.

What were the symptoms of the black plague?

First, Swelling called buboes appeared in the victim's armpits and groin. These were usually about the size of an egg but could sometimes be big as an apple. Then Bleeding under the skin caused dark blotches all over the body. The disease attacked the nervous system causing the victim to suffer spasms leaving the victim in terrible pain. Sometimes the buboes burst and a foulsmelling black liquid oozed from the open boils. When this happened the victim usually lived. However, in most cases, the victim suffered a painful death.

Distillation Experiment

Today we are doing a Distillation experiment which includes Evaporation + Condensation. Evaporation is when liquid is turned into gas using heat in this experiment this is used to make a solid like the last experiment (Separating a mixture using evaporation). Condensation is when gas is turned into a liquid which his cooling the energy. Combined together this is called Distillation.

Aim: to separate a solution (Coke/Coke Zero) to form a solid + a Liquid.

Hypothesis: I think by evaporating the coke method. That both cokes will turn into a clear colour and make one of the coke a solid and liquid in the boiling tube because of the Distillation.

Using classic coke

Observations: Our observation was that when the coke started boiling. The steam from the gas bubbles started going through the tube into the boiling tube (evaporation). When the steam went into the boiling tube, the beaker full of ice went under the boiling tube and it started cooling/condensing the gas, making the gas turn to liquid again, but this time the liquid was more clear than coke. After the coke turned into a sludge-like material. This is Distillation.

Conclusion: My hypothesis was kind of correct I think. What happened was that the bunsen burner was making the flask full of coke boil. Then the gas bubbles started making steam then the tube started bringing the gas towards to boiling tube with the ice then condensing the gas
