The person involved in an activity as shown in the picture above represents scuba diving which is one of the real life applications of boyle’s law.
According to boyle’s law-
P1 X V1 = P2 X V2.
Hence, now after putting the numbers-
1.0 X 2 = 3.0 X V2.
Now, rearrange the numbers so that we have V2 on one side and the rest of the numbers on the other side of the equals symbol.
V2 = 3.0 X 2/ 1.0.
V2 = 6cm3.
