1. In an experiment, a thin copper wire with weights at either end is placed on a supported block of ice. The thin wire is observed to pass through the ice. The experiment shows that an increase in _______.   pressure causes the freezing point of water to rise above 0o   specific latent heat causes the freezing point of water to rise above 0o   pressure causes the freezing point of water to drop below 0o   specific latent heat causes the freezing point of water to drop below 0o   Hint Half-n-half Clue   2. Ice is formed due to a change of state from liquid to solid.   True   False   3. Frost is formed due to a change of state from vapor to solid.   True   False   4. Snow is formed due to a change of state from liquid to solid.   True   False   5. Vaporization point and _______ have the same numerical value.   melting point   fusion point   liquefaction point   solidification point   Half-n-half Clue   6. The process by which a _______ changes into its gaseous state at a certain fixed temperature by the absorption of heat is called vaporization.   solid   liquid   7. The heat gained or lost by a body during a change of state is the product of its _______ and the specific latent heat.   Weight   Volume   Mass   Half-n-half Clue
