Have you seen or done an experiment about a balloon that is filled with water and does not burst when subjected to fire? Amazing, is it not? It may sound unbelievable because we all know that a balloon is very fragile. As such, a balloon can easily pop up when exposed in fire.
This is called
heat energy capacity of a
water-filled balloon. This takes place when a balloon that is filled with water and inflated with air is placed near or under fire. Take note that this balloon really does not pop at once unlike balloons that are not filled with water. When the rubber becomes hot, the balloon breaks.
The water within the balloon becomes hot until such time that it can no longer hold or control the pressure. At this point, the
hot temperature of water inside is transferred to the rubber balloon. As a result, the balloon finally breaks. But, when you place a fire directly under a water-filled balloon, the balloon really does not collapse or break because it is the water, and not the balloon, that absorbs heat. This is so because water has a heat capacity that is the reason why it absorbs heat.
