The best way to make an accurate measurement of the height of a polar liquid is to take the reading from the lowest point of the meniscus.
<h3>What is the meniscus of a liquid?</h3>
The meniscus of a liquid is a curved that occurs at the top of a liquid placed in a container as a result of the attractive forces between the molecules of a the liquid.
Polar substances such as water have a concave meniscus as they dip downwards.
Therefore, the best way to make an accurate measurement of the height of a polar liquid is to take the reading from the lowest point of the meniscus.

Answer:
H-CL
Explanation:
Hydrochloric acidis an acid wiith a diatomic molecule, consisting of a hydrogen atom H and a chlorine atom Cl connected by a polar covalent bond
2.1 L
P1V1 = P2V2
P1 = 3.5 atm
V1 = 4.2 L
P2 = 7.0 atm
V2 = ?
Solve for V2 —> V2 = P1V1/P2
V2 = (3.5 atm)(4.2 L) / (7.0 atm) = 2.1 L
