Can you me with this i really appreciate it

What happens to the temperature of a substance when the average kinetic energy of its particles increases?

Substance a is a nonpolar liquid and has only dispersion forces among its constituent particles. substance b is also a nonpolar liquid and has about the same magnitude of dispersion forces among its constituent particles. when substance a and b are combined, they spontaneously mix.
