How do the melting points of helium, lithium, beryllium, and carbon relate to their positions on the periodic table?
A as the number of protons increases, the melting point decreases
B as the number of protons decreases, the melting point decreases
C as the number of protons increases, the melting point increases
D as the number of protons decreases, the melting point increases

The kinetic energy of the liquid increases. hope this !

Answer:             1.0  × 10⁻⁵ msolution:                     as we know ph is given as,                                    ph  = -log [h⁺]and,                                    [h⁺]  =  10^-ph    (1)putting value of ph in eq. 1,                                    [h⁺]  =  10⁻⁵                                    [h⁺]  =  1.0  × 10⁻⁵ m
