intermolecular forces (IF) and internal kinetic energy (KE)

If IF=KE , then in what state of matter is the substance?

plasma

gas

solid

liquid

 

i was thinking liquid but isnt liquid ....  IF is greater than or equal to KE

I believe it would be plasma.   

 

 Re-thought my answer....

KE is the temperature measure of a substance

 

Start with a solid....heat it up ....the KE increases

    if the KE increases enough , the soldi melts and becomes a liquid

       heat it more and the KE overcomes the INTERmolecular forces holding the substance together and it becomes a gas

           where intermolecular forces ae negligible

                 heat the gas up a lot more and INTRAmolecular forces are overcome and you get a plasma of electrons and ions.....

 

So I would say     the answer you need is GAS !     sorry.....didn't think it tthrough...

Jenny, I don't understand a word of this.....but, depending upon what you might trust, here's what this website says  :
