<span>Kwang Jeon observed that Amoeba had been attacked by a bacterial infection, and lots of the Amoeba had
died. However, some survived and continued to reproduce. After investigating the remaining
Amoeba and their offspring, he noticed they were very healthy. He thought maybe they were able to
fight off the bacteria, but instead, he found they were still infected with the bacteria but were not
dying. The bacteria were no longer making the Amoeba sick. Then, he killed off the bacteria using
antibiotics and was surprised to see that the Amoeba also died. It seemed the Amoeba and bacteria
had formed a relationship in which they both needed each other to survive. After researching, Jeon
found that the bacteria made a protein that the Amoeba needed to survive. </span>
Boyle's law of ideal gas: This law states that the volume of a gas is inversely proportional to its pressure at a constant temperature. Acc to this law we can write the relation of pressure and volume as:
That means:
From that equation we can calculate Volume of gas at a certain pressure:
P₁=Initial pressure
V₁=Initial volume
P₂=Final pressure
V₂= Final volume
Here P₁, initial pressure is given as 85.0 kPa
V₁, initial volume is given as 525 mL
P₂, final pressure is 65.0 kPa
so,
V_{2}=85\times 525\div 65
=686 mL
Volume of gas will be 686 mL.
Answer:
0.6364 g/cm^3
Explanation:
Density = mass/volume
Where mass = 5.6g and...
Volume = (33.9 - 25.1) = 8.8ml
Where 1ml = 1 cm^3
Density = 5.6/8.8 = 0.6364 g/cm^3
