1. Compare One column of water has twice the diameter
as another water column. If the pressure at the bottom
of each column is the same, how do the heights of the
two columns compare?
2. Explain why the height of the liquid column in a
barometer changes as atmospheric pressure changes.
3. Classify the following as fluids or solids: warm butter,
liquid nitrogen, paper, neon gas, ice.
4. Explain how the pressure at the bottom of a container
depends on the container shape and the fluid height.
5. Think Critically Explain how the diameter of a balloon
changes as it rises higher in the atmosphere.

The boiling point of propanoic acid is higher than that of 1-butanol because: propanoic acid has a higher molecular weight than 1-butanol. propanoic acid is more soluble in water than 1-butanol. propanoic acid is a better hydrogen bond donor than 1-butanol. propanoic acid forms hydrogen bonded dimers and 1-butanol does not. 1-butanol forms hydrogen bonded dimers and propanoic acid does not.
