Problem: Which of the following is true for the solubility of NaCl(s) and CH4(g) in water?A) Increasing the temperature will increase the solubility of CH4 B) Increasing the temperature will decrease the solubility of NaCl C) Both NaCl and CH4 are very soluble in water D) Neither NaCl nor CH4 are very soluble in water E) None of the above

We are asked which of the following is true for the solubility of NaCl(s) and CH4(g) in water.


The solubility of the majority of substances increases as the temperature increases. 

  • An increase in temperature increases kinetic energy.
  • Higher kinetic energy causes more motion in the molecules which break intermolecular bonds.


NaCl(s) and CH4(g) solubility both increase when the temperature is increased.

NaCl(s) → soluble salt

CH4(g) → non-polar → not soluble in water
