5 True/False Question

1. vaporization → when vaporizationoccurs at the surface of a liquid that is not boiling
   

   True        False

2. amorphous solid → the force exerted by a gas per unit surface area of an object
   

   True        False

3. kinetic theory on collisions of gas particles → perfectly elastic because kinetic energy is transferred without loss from one particle to another and the kinetic energy remains constant
   

   True        False

4. allotropes → measures atmospheric pressure
   

   True        False

5. the temperature at whichthe liquid and solid states of a substance are in equilibrium is the same as → the melting and freezing point of the substance
   

   True        False
