b. Which of the following statements is true?
A) The average kinetic energy of the ice in cup A is less than that in cup
b.
B)The average kinetic energy of the ice in cup A is greater than that cup in
b.
C)The average kinetic energy of the ice cup A is equal to that in cup
b.
D)The average kinetic energies of the ice in cup A and the ice in cup B are not comparable.
Average kinetic energy is given by the formula:
KE(average) = 3/2*k*T
where k = Boltzmann constant = 1.38*10⁻²³ J/K
T = temperature in Kelvin (K)
Thus, the average KE is dependent only on temperature and independent of mass.
Since the temp in Cup A and B remains the same, the average KE will also be the same.

c. [H+] is less than [OH−].
d. [H+] is greater than [OH−].
