Answer:
Distillation
Explanation:
The method of distillation can be used to separate the two liquids, if their boiling point is known. The liquid with lower boiling point will be evaporated and its vapours will be captured, while the liquid with higher boiling point will remail in the container in the liquid state.
Well one mole of stuff, any stuff, including carbon dioxide, specifies

0.5 kg block of aluminum (caluminum=900J/kg⋅∘C) is heated to 200∘C. The block is then quickly placed in an insulated tub of cold water at 0∘C (cwater=4186J/kg⋅∘C) and sealed. At equilibrium, the temperature of the water and block are measured to be 20∘C.
If the original experiment is repeated with a 1.0 kg aluminum block, what is the final temperature of the water and block?
A. less than 20∘C
B. 20∘C
C. greater than 20∘C
Answer:
Option C is correct
Explanation:
Increase in the mass of aluminium block would increase the heat capacity of block isothermaly before immersed in water at 0° so heat available for transfer is higher so equilibrium temperature of system would increase.
WBC's that stands for white blood cells, that are cells of the immune system. It helps to protect the body from various infectious diseases. There are different types of white blood cells in the body like T cells, B cells, monocytes etc. And is circulated in the body by the circulatory system and thus helps in the recovery from the infection.
Thus, immune and circulatory are two organ systems that are involved in the recovery of the infection.
