18. a little league baseball team were playing back to back games last saturday. one of the adults was in charge of bringing cold drinks for the team. after arriving at the game, the adult pulled a cooler full of drinks from the back of their car and poured two bags of cold ice into the cooler, filled it the rest of the way with drinks, and placed the cooler by the bleachers. two and half hours passed when the adult opened the cooler to allow players to pick their drinks. the adult was surprised to see the drinks floating in the bottom of the cooler. what happened to the ice that was poured into the cooler and why is there a pool of water in the bottom? use what you know to answer the question. then, predict what would happen if the cooler had been left out until the end of the evening. use the following page, if necessary. (two points) answer in complete sentences.

Answer

Brief Explanations:

The ice underwent a phase change from solid (ice) to liquid (water) due to heat transfer. Heat from the environment (and possibly the drinks) caused the ice to melt. If the cooler had been left out until the end of the evening, more heat would have been transferred to the ice (and then to the water formed from melted ice). Eventually, if enough heat was absorbed, the water (from melted ice) could have evaporated (a liquid - to - gas phase change). But since the cooler is a closed (relatively) system for the short - term (evaporation would be slow compared to melting), most of the remaining ice (if any) would melt completely, and the water level would be higher.

Answer:

The ice melted because heat was transferred to it, changing it from a solid to a liquid, which formed the pool of water. If left until the evening, all the ice would melt (assuming no refreezing conditions), and the water volume would be at its maximum from all the melted ice.
