Nonpolar aromatic compounds were separated by HPLC on an octadecyl (C18) bonded phase. The eluent was 90 vol% methanol in water. How would the retention times be affected if 65% methanol were used instead?

conduction is the transfer of thermal energy (heat in transfer) due to collisions between the molecules in the object. collisions between adjacent atoms and molecules transfer kinetic energy from the warmer to the cooler object. the objects must be in physical contact.
