Give the uses of dry ice?
Dear Student,
Uses of dry ice :
1. To pack in "coolers" with food, or other products which require being kept frozen.
2. To place in deep freezers or refrigerators during times when electricals power is off.
3. To add to party punch bowls to provide a bubbling, heavier than air "fog" creating "spooky" visual effects.
4. To chill very close tolerance mechanical parts to slightly "shrink" them in order to allow them to be inserted into holes [or openings] into which they would not fit at normal ambient temperatures.
5. To insert [as far as possible] into a water pipe which has had a section cut out for replacement, and requires some way to prevent the slight seepage of water into a new "sweat" connection while it is being soldered.
Regards,
