Answer: d. None of the above is false.
Explanation: The reasons are:
Intermolecular forces should be reduced when molecules need to be vaporized, otherwise they will not be converted into vapours.
When the temperature increases, forces of attraction decreases which allows molecules to evaporate because energy will be increased which allows molecule to break bonding between them. Hence increasing temperature has effect on vaporization.
Dispersion forces is the weakest force between molecules and hydrogen bond is strong so molecule having only dispersion force will evaporate at the higher rate.
Answer:
H+
Explanation:
Hemoglobin is the major protein of red blood cells. It has many exposed amino groups and carboxylic groups at its surface. These NH3 and COOH groups serve as weak acids and bases respectively and allow hemoglobin to serve as a buffer to maintain the pH of the RBC cytoplasm.
As the exposed amino groups of hemoglobin protein bind to the H+ ions, the free H+ concentration of the cytoplasm of RBC is reduced leading to a buffer action to maintain the pH.
Answer:
Most of the world's weather originates in the troposphere, a second scientist tells Carbon Brief, meaning that changes to seasonal temperatures could be affecting the likelihood of extreme weather events, such as flooding and drought.
