At 83 degree celsius, Substance E has a vapor pressure of and Substance F 129 torr has a vapor pressure of 159 torr. Which has a higher enthalpy of vaporization?

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.
