When first blown up, a balloon is firm because of the air pressure inside it. However, after time, the balloon becomes soft as the air pressure inside drops. What could have caused the air pressure to decrease?

• increase in air temperature

• decrease in the balloon's volume

• decrease in the number of air particles as they leaded out of the balloon

• a chemical reaction between the air particles & the balloon
