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.

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 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.
