One balloon was only partly filled when put on the plane. during the flight, the balloon volume
increased from 7 l at 1.0 atm to 9 l. what was the cabin pressure on the airplane during the flight?
(assume the balloon stretched very easily and the temperature was constant.)

P₂ = 0.8 atm

Explanation:

Given data:

Initial pressure = 1 atm

Initial volume = 7 L

Final volume = 9 L

Final pressure = ?

Solution:

P₁V₁ = P₂V₂

P₁ = Initial pressure

V₁ = Initial volume

P₂ = Final pressure

V₂ = Final volume

Now we will put the vales in formula.

P₁V₁ = P₂V₂

P₂ = P₁V₁ /V₂

P₂ = 1 atm × 7 L / 9 L

P₂ = 7 atm. L / 9 L

P₂ = 0.8 atm

cytokinesis is the splitting of a cell membrane to form 2 identical daughter cells. it's similar to mitosis as both cells have identical copies of dna and cytokinesis is a step in the mitotic cycle.

> b takes place in the gas phase in an isothermal tubular reactor. the feed is one mole of a per one mole of c, an inert. the entering temperature and pressure are 427°c and 10 atm, respectively. the gas constant r = 0.08206 atm · l/mol · k.
