Mini Quizzz:
Use KPT to explain what happens to the particles
- When an ice cubes melts
- When water boils
When heat is supplied, water molecules gain energy and vibrate faster about their fixed position
When solid water molecules gain sufficient energy to overcome the hydrogen bonding that hed them in fixed positions,
the water molecules will move slightly apart and now roll and glide over each other (LIQUID)
Water molecules gain energy, they move faster and further apart
When water molecules gain sufficient energy to completely overcome the hydrogen bonding between the molecules,
the water molecules move far apart and away from each other . (GAS)
melting point/ boiling point --> shows that heat is about to break up the bonding
* bond between water molecules = hydrogen bond
Condensation
- loses heat to the surrounding
* think about freezing , condensation and sublimation
