11.1 States and State Changes
Transcript of 11.1 States and State Changes
Think About it
Define surface tension. What state of matter is associated with it?
What sort of changes take place as ice at 0 degrees melts?
Which has a greater entropy, a substance in a liquid state or the same substance in a gaseous state?
How do states of matter differ?
What are the ways that liquid changes to a gas?
Special Liquid Behavior
adhesion and cohesion
both of these forces work together in capillary action
Cohesion is the culprit in surface tension- when liquids decrease their energy by decreasing surface area
