Ion–dipole forces always require _____. a. an ion and a water molecule b. an ion and a polar molecule c. a cation and a water molecule d. an anion and a polar molecule 4. Which of the following is the correct statement about the effects of temperature (T) on the average kinetic energy of gas particles (KE)? a. increase in T → decrease in KE b. increase in T → no effect on KE c. decrease in T → increase in KE d. decrease in T → decrease in KE 5.
