1. Dr. Brown's science class is studying changes in particle motion during phase changes by adding a few pieces of dry ice to a flask and covering it with a balloon. After a few minutes they observed the balloon starting to inflate. Predict what will happen if they put the flask with the inflated balloon into the freezer.
No change occurs.
The balloon will deflate.
The dry ice precipitates.
The balloon inflates further.

After a few minutes they observed the balloon starting to inflate. Predict what will happen if they put the flask with the inflated balloon onto a hot plate and raise its temperature from room temperature to 40 °C.
No change occurs.
The balloon will deflate.
The dry ice precipitates.
The balloon inflates further.
