|
Particles in all forms of matter that are in constant motion.
|
|
|
What is kinetic energy?
|
the energy an object has because of its motion.
|
|
|
What are the differences between spacing of particles and movement of gases,liquids,& solids.
|
gases:very far apart,rapid movement in random directions
liquids:particles very close to eachother,slide past eachother solids:packed tightly together,locked in a fixed position(vibrate back and forth) |

|
Define boiling point and what is unique about the normal boiling point?
|
boiling point is the temp. at which the vapor pressure is equal to the external pressure. Normal boiling point=pressure at sea level(101.3kPa)
|
|
|
define vapor pressure.
|
vapor pressure is a force due to a gas above a liquid.
|
|
|
What is absolute zero and what is the temperature?
|
absolute zero is when particles w/ no kinetic energy that are not moving. temp.=0 kelvin
