Question

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

please wait, I'm trying to solve your question

anonymous · Answer

okay:)

michele_laino · Answer

since the liquid state is a bonded state, namely the molecules of a liquid are  bonded each to other, then I think the fourth option, namely:
IF> KE

michele_laino · Answer

I'm not sure, since a liquid can evaporate, so maybe the third option is possible too

anonymous · Answer

ohh okay, but mainly the fourth option?

anonymous · Answer

and also, there is this last problem that also has the same answer choices as the above one..

How do intermolecular forces (IF) and internal kinetic energy (KE) compare in gases?

which would this one be?

michele_laino · Answer

I think the third one, since each liquid can evaporate at any temperature

michele_laino · Answer

for gases the answer is simple, we have:
KE > IF

anonymous · Answer

okay!

so for the first one in comparison to liquids, we have choice C?
and the second one in comparison to gases is choice A?

michele_laino · Answer

yes!

yay!! thank you very much!:D
