Two balloons are inflated to an equal volume. Balloon 2 is place in the freezer for 20 minutes.  Why would freezing a balloon produce the results shown in balloon 2?

• Increased kinetic energy decreases the attraction between particles inside the balloon.
• Increased kiteic energy increases the attraction between particles inside the balloon.
• Decreased kinetic energy decreases the attraction between particles inside the balloon.
• Decreased kinetic energy increases the attraction between particles inside the balloon.
