5
Q
Gas particles
A
Far apart, not touching, lots of kinetic energy, moving a lot
6
Q
Why do temperatures remain constant when a solid is being heated
A
The particles gain energy but the energy is needed to overcome the forces holding the particles together. Once all the forces have been broken, the temperatures will increase again
