A balloon is filled with helium in an airplane, where the air pressure is 81 kPa. The filled balloon has volume of 4.2 L. When the plane lands, the cabin is depressurized to the outside air pressure, which is 94 kPa. If the temperature of the balloon remains the same, what is the new volume of the balloon?

3.62L

Explanation:

Using Boyle's law equation i.e

P1V1 = P2V2

Where;

P1 = initial pressure

V1 = initial volume

P2 = final pressure

V2 = final volume

According to information provided in this question, P1 = 81kPa, P2 = 94kPa, V1 = 4.2L, V2 = ?

P1V1 = P2V2

81 × 4.2 = 94 × V2

340.2 = 94V2

V2 = 340.2/94

V2 = 3.619

V2 = 3.62L

cell division has two checkpoints namely, g1

checkpoint and spindle assembly checkpoint. the checkpoint which determines if

division has properly occurred is the g1 checkpoint. at this point, is a damage

in the dna is detected or  the has not reach the optimum size, the cell is

stopped in g1 and is not allowed to proceed to further process.
