Question

Atmospheric pressure decreases as altitude increases. In other words, there is more air pushing down on you at sea level, and there is less air pressure pushing down on you when you are on a mountain.If pentane (C5H12), hexane (C6H14), and hexanol (C6H13OH) are heated evenly at different altitudes, rank them according to the order in which you would expect them to begin boiling.

1. Hexane high altitude.
2. Pentane high altitude.
3. Hexane sea level.
4. Hexanol sea level

Answer 1

Boils first >Pentane at high altitude> Hexane at high altitude>hexane at sea level> hexanol at sea level> boils last.

Explanation:

Step 1: To boil, a liquid must overcome the attractive forces between molecules and the outside pressure pushing down on the liquid's surface.

(Hexanol> Hexane> Pentane)

Step 2: Identify which situation is most conducive to boiling

To boil, a liquid must overcome the attractive forces between molecules and the outside pressure pushing down on the liquid's surface.

In which situation would you expect the liquid to boil first, assuming equal heating.

(weak intermolecular attraction and low atmospheric pressure)

Answer 2

step 2 then step 1 then step 3 then step 4

Step-by-step explanation:

First boil it. Then identify the situation which is most conducive to boiling .

While this, a liquid must overcome the attractive forces between molecules and the outside pressure pushing down on the liquid's surface.

The liquid will boil when there is weak intermolecular attraction and low atmospheric pressure.

Steps to be followed:

Pentane at high altitude

Hexane at high altitude

hexane at sea level

hexanol at sea level
