Question

Explain the following phenomena:

a. the cloud formation when you open a beer bottle

b. the fact that we can blow hot and cold air through our mouth

c. the desert effect: one side of a mountain is covered with vegetation while the other has very little or no vegetation

d. the fact that it is colder on the top of a mountain than it is at the bottom, despite the top being closer to the sun

Answer 1

a)

"clouds" form since CO2 gas which was dissolved in water is now going to the "gas" phase, then the CO2 will be seen as "cloudy" which is true, sinc e CO2 is now from (aq) --> (g)

b)

We blow "cold" air, since it is recently in the mouth, so we take out the air which has not been "heated"

For "hot" air, we take it form our guts, which is at 37°C so it is "warm"

c)

this might be due ot the fact of water movement/sunlight

d)

it is colder, due to the pressure present, since it has lower mass of air, the heat exchange is lower, therefore, lower Temperature is experienced....

Also note that sunrays will "bounce" form the floor and will re-heat the air at bottom surface
