I Need Help With HW!!!! (7th grade science)?
I REALLY don’t get science can you help me with this question At camp Derek and his friends hiked up to a forest-fire lookout station at an elevation of 2445m. On tp of the mountain, Derek drank the last of the water he carried in a plastic bottle. He put the lid back on the bottle, tossed it in his day pack, and forgot about it. When Derek returned home to Seattle 3 days later, and unpacked his stuff, he found his water. It looked like this. (a pic of a water bottle squished) Derek thought,
I must have sat on my water bottle, ot somethine, to squish like that.
When he unscrewed the lid, he heard a hissing sound, and the bottle slowly returned to its proper shape. What do you think happened to Derek’s bottle? Can you explain Derek’s squashed bottle and the hissing sound?
If you think answering this question is like cheating for me. Then can you e-mail me and try to help me with it.
Thank You,
Izzy

Okay, you can research this.
It’s all about ATMOSPHERIC PRESSURE. The words “at an elevation of 2445m” are key figures to this problem! 😉
Try reading on wikipedia.org, dictionary.com, or any other resource! This topic is truly interesting.

to refrase the question, what would make a deflated contained hiss when you open the lid????? ((((its sucking in air to return to its former shape in which the container does not physically stress being under))))
