Need some help answering a question that will be simple for you guys.

[IWD]

So here's the question, I'm new to chemistry and this is a first year college level course. i've aced everything so far, but I can't seem to figure out this KMT stuff as quickly as I have to. I understand most of it, but I'm struggling with this question, which I believe will be easy as hell for most of you, as most of the people in this forum are incredibly smart when it comes to this stuff.

3. Explain, using the KMT, why, when you’re drinking a liquid with a straw, the liquid goes up the straw.

Now, I believe I can explain this, but I'm not sure how to relate it to the kinetic molecular theory. To those of you that are really good with this stuff, what should I put for my answer? It's the last question on a huge assignment that I've completed with ease all of the way up to here. My computer that had my chemistry stuff on it was broken for about a month, and I forget a lot of the KMT stuff and I don't have that much time. I don't see how this relates to KMT at all.. I'm sure there's a reason, I'm just rushed and it's not clicking.

Thanks to anyone that can help. It should be a simple answer to those of you who know it, and lots of thanks will be awarded to anyone who can help me with it.

Alright guys, I figured it out and found the answer in my notes I had written about a month ago, but, there's no sense leaving any question in regards to any field unanswered on a site that's all about information, so we might as well have the answer up on here so amateur chemists can learn about this stuff.

I might post the answer myself but I'm really busy with this schoolwork right now. It will have to be later unless one of you can come up with it, or have the time to.

This. Brief explanation because I have schoolwork as well: Gas expands to the volume of container with a proportional change in pressure according to Boyle's Law, P₁V₁=P₂V₂. Expanding diaphragm causes pressure decrease. Air exerts a pressure on the sample of liquid equal to the ambient atmospheric pressure. When water is exposed to two separate bodies of gas at different positions on the surface, the level of water will rise or fall in the different areas in such a way which equilibrates the pressure between the system, making them equal.

Hence, the water rises up the straw to push against the vacuum and bring the pressure in the diaphragm up to ambient pressure.
