because the moon rotates on its axis at the same rate that the moon orbits the earth – a situation known as synchronous rotation, or tidal locking. the moon is directly illuminated by the sun, and the cyclically varying viewing conditions cause the lunar phases.
answer: decreasing pressure
explanation: solubility of a gas is governed by henry's law.
according to henry's law, the solubility of a gas in a liquid is directly proportional to the pressure of the gas in equilibrium with the liquid at that temperature.
where, = mole fraction of gas in the solution
= partial pressure of the gas above solution
the solubility of gas increases with decrease in temperature.
thus the solubility of gaseous solute will decrease when the pressure is decreased.
a). carbon enters the atmosphere as carbon dioxide from respiration and combustion.
