Question

In which of the following states of matter are the intermolecular forces much greater than the internal kinetic energy?

solid

liquid

gas

plasma



Which of the following states of matter is always a good conductor of electricity?

solid

liquid

gas

Answer 1

1. solid 2.plasma ??

Answer 2

@petiteme

Answer 3

do you know what "intermolecular" forces represent?

Answer 4

Well it's not in my notes but I am guessing it's the molecules inside that attract atoms

Answer 5

I recall that for solids it said that IF > KE so I'm guessing its solid for the first

Answer 6

How can you compare forces with energies?

Forces and energies are entirely different things.

Answer 7

that's what it says in the notes that teacher told us to write down and what we're studying

Answer 8

"molecules and atoms attract each other through intermolecular forces" solids - IF>KE

Answer 9

so 1.solid 2.plasma is that correct?

Answer 12

helloo?

Answer 13

The molecules are attracted to one another if you try and pull them apart and repel one another if you try and push them together.
There is a position when the net force between the molecules is zero and this is at their equilibrium spacing.

To separate molecules from their equilibrium separation energy must be supplied and this is the internal kinetic energy.

So in which of the states of matter is there not enough energy to break the bonds between molecules?
