Judge each of the statements below as T (true) or F (false). The one (s) that are false,
justify the reason objectively and precisely (up to 4 lines, maximum). F (false) answers
without justifications will not be considered.
() An ideal gas always behaves like a real gas in high pressure regimes.
()A real gas always behaves like an ideal gas in low pressure regimes.
() Oxygen cylinders, used to deliver 02 to patients who need it, contain 02
compressed and pressurized. When we open the valve on a cylinder to deliver 02 to a
patient, and so to raise its partial pressure in relation to the partial pressure of O2 in the
atmosphere, the gas does a reversible positive work against the atmosphere.
() When opening the cylinder valve in the previous item, the gas temperature remains
constant and equal to room temperature, since there is no heat exchange between the gas
and the environment.
() New variants of coronavirus (Sars-Cov-2) have been appearing lately as a result of
its uncontrolled transmission, which increases the likelihood of transcription errors
highly viable for the survival of the virus. Sars-Cov-2 is known to bind to the human protein
ACE2 (present in lung cells) through the binding domain of its Spyke protein. In variants
more transmissible, Spyke-ACE2 interactions are stronger than in less transmissible
variants. At stronger interactions in the most transmissible variants are due to mutations of
amino acids in the Spyke that result in more favorable interactions with ACE2 (such as
electrostatic interaction between Asp (negative) and Lys (positive). When a mutation occurs
that intensifies the Spyke-ACE2 interaction, we can say that the potent variant is capable of
generating a greater entropy increase in the neighborhood than the original variant, where
neighborhood would be everything beyond the Spyke-ACE2 complex.
