why does a can of soda explode in a hot car? As the temperature rises, the gas (carbon dioxide that make the fizzle in soda pop)exerts more and more pressure until the container ruptures. Any gas heated tries to expand due to greater molecular motion.If it is contained, it ...

when pressure decreases what happens with the boiling point, it decreases, increases or stays the same? I read the book (the example used is water) were it says that if vapor pressure is less than the pressure pushing down on the surface the bubbles formed collapse; but when ...

It decreases? If the air pressure increased, wouldn't that make the diver go down? What happens when you press on the pressure cap? Oh, yeah. So, at night the atmospheric pressure increases and therefore the diver sinks? Can someone help me with this question about a Cartesian...

Okay, I was taught that if a geometric series is infinite and it diverges then it has no limit and no sum. Looking back in my notes, I found an example of finding the value for a divergent series? Is this possible? The sum of an infinite geometric progression is infinite when ...

WHY CAN'T HUMANS LIVE ON VENUS? Too hot, no oxygen and very high atmospheric pressure. But this doesn't mean that we could live there, it only means that we can't walk on the surface without protection. Thank you for using the Jiskha Homework Help Forum. Well, life on Venus "...
