Answer: Energy is absorbed, and kinetic energy increases
Explanation: Boiling is the phenomenon in which liquid is converted to gaseous state.
Thus in order to break the inter molecular forces of attraction present in a liquid, energy is required and thus the process is endothermic in nature.
As the molecules absorb energy, the kinetic energy of the molecules increases and they start moving faster and more randomly and convert into gaseous state.
Explanation:
Strong acids are those that are completely ionized in body fluids, and weak acids are those that are incompletely ionized in body fluids. Hydrochloric acid (HCl) is considered a strong acid because it is present only in a completely ionized form in the body, whereas carbonic acid (H2 CO3) is a weak acid because it is ionized incompletely, and, at equilibrium, all three reactants are present in body fluids. See the reactions below.
H2 CO3 (acid)↔H+ + HCO3- (base)
