Heat that flows by conduction is the transfer of thermal energy between substances in contact. What must occur for this to
happen?
The two systems must be the same temperature.
The two systems must not be touching each another.
Q One system must have higher kinetic energy than the other system
O'The thermal energy of one system must be the same as the thermal energy of the other system

Yeah, but what are you trying to ask?

The answer is nitrogen-containing bases

Just took the quiz on edgenuity and the correct answer is "c.  4.54 x  10–12  j"

Vander waals forces are inter molecular bonds that exist within molecules of the same substance. a water molecule is made up of oxygen and hydrogen atoms which share electrons between each other. the vander waals forces are forces that exist between multitude of different  molecules of water. dipole dipole forces is the type of vander waals force that exist in water. the oxygen atom which is more electronegative pulls the shared electron closer to itself thus generating a partial negative charge while the hydrogen acquire a partial positive charge. these two different charges causes attraction to occur in water molecules.
