Describe the particles in model.

• Definite shape and definite volume, close together, slow movement of particles bumping into each other.
• No definite shape, but has a definite volume and some space for particles to flow freely allowing the substance to move
• No definite shape or definite volume, lots of space between particles, particles moving very fast all over

One sunny morning a boy left a shallow bowl of water on the window ledge in his kitchen.  He meant to put the water on the floor for his cat. When he returned home from school, most of the water was gone. Which process has occurred?

• Condensation
• Liquification
• Evaporation
• Boiling
