Q:

A volatile liquid with vapor pressure 85 kPa (at sea level, 25° C) is taken to the peak of Mt. Everest. Which of the following is true?

A) The vapor pressure of the solution decreases B) The solution will condense quickly than when at sea level
C) The solution will vaporize quickly than when at sea level D) The vapor pressure of the solution increases
 
Answer & Explanation Answer: D) The vapor pressure of the solution increases

Explanation: The vapor pressure of a liquid is independent of the pressure of surroundings. Any solution boils when its vapor pressure equals the surrounding atmospheric pressure. The atmospheric pressure decreases with increase in altitude. Due to this, the vapor pressure equals the atmospheric pressure in a shorter period of time when compared to at the solution being present at sea level. Therefore, the solution will vaporize quickly as the bowling point will reached faster.

Q:

All macromolecules are polymers.

A) True B) False
 
Answer & Explanation Answer: B) False

Explanation: Polymers consists of thousands of repeating units, and are macromolecules because of their very large size and high molecular mass (10³ to 10? u). However, a macromolecule may or may not contain repeating monomer units (for example, chlorophyll). Therefore, all polymers are macromolecules, but all macromolecules are not polymers.
