Answer:
1.38 atm
Explanation:
Using Boyle's law which states that the volume of a given mass of gas is inversely proportional to the pressure, provided temperature remains constant
P1V1= P2V2
P1 = 2.2 atm, V1 = 2.5L ,
P2 = ? , V2 = 4L
2.2 × 2.5 = P2 × 4
Divide both sides by 4
P2 = 5.5 ÷ 4
P2 = 1.38 atm

Answer:
C Condensation of water vapor
Explanation:
One of the components of the atmosphere is water vapour. Water vapour is always present in air.
This water vapour may combine with particles of dust and smoke and condense around them to form clouds.
As more water vapour condenses and coalesces, the clouds become thicker and precipitation eventually follows.
