Bring a large pot of water to just to a boil. You want enough water to comfortably hold all the shrimp. There should be about 1 to 2 inches (2.5 to 5.1 cm) more water than there is shrimp.
The amount depends on the type of mineral. A large group of minerals  the opaque minerals  do not transmit significant light, even in thin section. These minerals do, however , reflect light back that can tell us a great deal about their identity and origin. These minerals typically have significant metallic bonding (e.g., native elements, sulfides, oxides).
When the warm air comes in contact with the cold glasses it transfers some heat energy to the glass and results in formation of a thin foggy layer it. When the glasses also get heated up then the thin layer on the glasses will evaporate clearing the vision through the glass. The fog disappears due to the warming up of glasses. The effect of the humidity in the room on the very cool eye glasses brought into the room can be studied by an experiment. If the air inside the room is warm and generates more water vapor, the vapor pressure of the inside air becomes higher.
