How do intermolecular forces (if) and internal kinetic energy (ke) compare in liquids?
a. if < ke

b. if = 0, ke is large

c. if ≥ ke

d. if > ke

I am sorry this is a bit late! I hope it is still relevant! So, when you have a liquid, we know that the molecules are able to slide past one another, however they are still pretty tightly compact in comparison to a gas' molecules. So since the molecules are not able to move freely, we know that the intermolecular forces must be at least equal, if not stronger than the kinetic energy. This means that our correct answer would be C. 

The intermolecular forces and kinetic energy in liquids can be written as: IF≥KE

1) when you rub your hands together quickly, the kinetic energy is converted to mechanical energy.2) thermal energy from the sun travels to earth as infrared waves.3) energy is transferred through the matter of space by electromagnetic waves. 4) when a match is burned, chemical potential energy is converted to thermal and radiant energy. 5) seismicwaves are caused by back and forth movement , or vibration, of an object. 6) mechanicalenergy in an engine changes thermal energy into kinetic energy to make a car move.
