Answer 2

Hello @dayana138 !
What do you think it should be ?

Answer 3

any guesses ?

Answer 4

I am waiting for ur response !

Answer 5

I'm not clear on the relationship between kinetic energy and intermolecular forces to beign with, and googling it makes me more confused. I guessed freezing but I dont really have a reason why .-.

Answer 6

alryt let's see

Answer 7

Boiling

When the kinetic energy of molecules increases, then the molecules or atoms gain enough energy to overcome the intermolecular force of attraction and will become free to move.
In case of liquid, the molecule overcome intermolecular force of attraction and changes to gaseous state.

Answer 8

Hope this helps... if not..please do let me know

Answer 9

The intermolecular force tends to bring the particles of a matter close to each other while kinetic energy tends to move them apart. It is the net effect of the two forces which decides the state of matter. When the temperature is sufficiently low, the kinetic energy is low and intermolecular forces bring them so close that they cling to one another and occupy fixed positions. At this stage the matter is in solid state. But as we start heating them, their (particles) kinetic energy starts rising and at sufficient temperature is able to overcome the intermolecular forces. Now the particles start moving away from each other. At this stage the matter is in liquid stage. If we heat it further then the particles will start moving randomly away from each other and ultimately gaseous state is achieved.

Answer 10

Now can you select the correct option ?
boiling-------> Liquid to gas
condensation----> Gas to liquid
freezing-------> Liquid to solid
solidification-----> Liquid/Gas to solid

So in nutshell,
Increasing kinetic energy changes the state from Solid to liquid and then from liquid to Gas.

Answer 12

Wait so, if kinetic energy is overpowering the intermolecular forces, would it in fact be boiling? And if thats true then intermolecular forces > kinetic energy would just be condensation? How would I be able to tell with freezing and solidification?

Answer 13

Yes, if intermolecular force > kinetic energy then the matter will condense, then freeze.

Answer 14

Here KE > Intermolecular force so the change will be in the direction of solid to gas and only boiling is the option which is in this direction. So boiling is the answer.

Alright thank you very much for your time and patience!
