Answer:
Explanation:
A) Hg is mercury, a metal that is mostly liquid at STP (Standard Temp and Pressure), though some small portion of it will be gaseous in a closed container.
B) CH Methylidyne radical is a gas
It is not a stable compound because carbon has four valence electrons and only one of those is kept occupied by the hydrogen atom.
If this is supposed to be CH₄ which is methane, then also a gas at STP
C) C₂H₅OH is ethanol which is mostly a liquid at STP, though some small portion of it will be gaseous in a closed container.
D) H₂O is water and will be mostly liquid at STP, though some small portion of it will be gaseous in a closed container.

Answer:
Air resistance
Explanation:
Despite the law of conservation of energy stating that energy can neither be created nor destroyed but can only be transformed from one state to another, some energy is usually lost in the process of transformation and its majorly attributed to frictional loss. Friction opposes normal movement hence in air, air resistance tends to reduce the original energy compared to the initial. That is why the final energy in this case is slightly less than the original energy.
Answer:
The correct choice is A. Yes, the more exercise the better.
