Freezing
The picture below shows the particles of which state?

What is the difference between evaporation and boiling
Evaporation happens without the addition of heat while boiling must have heat
What are particles?
Atoms and Molecules
The temperature at which solid change into liquid is called?
Melting Point
The process at which gas turn into liquid is called?
Condensation
When we add thermal energy, what happens to the attraction forces between particles?
Decrease, that's why particles can start moving around
When we remove thermal energy, what happens to the attraction forces between particles?
Increase, that's why the particles come close to each other
