Which of the Following Statements About Water Is True

Which of the Following Statements About Water Is Trueにまつわる役立つ知識を分かりやすく発信ます。

Here’s the biggest truth of all: water is essential for all known life. Every single living thing on Earth, from your houseplant to your grumpy cat, needs water to survive. Your body is about 60% water, which means you’re basically a walking water balloon. (A very smart water balloon that reads articles.)

So when a question says “Water covers about 71% of Earth’s surface”, that’s a true fact. But only about 2.5% of that is fresh water—the rest is salty ocean. So if you’re thirsty, don’t gulp from the sea. That’s how you become a salty, sad person. True statement: most of Earth’s water is salty, which is nature’s way of saying “drink responsibly.”

The Sneaky “pH Balance” Trick

Pure water has a pH of 7, which is neutral—not acidic, not basic. That’s why it tastes like nothing. (Unless you have a fancy water filter, in which case you’re a hydration hipster and I respect your commitment.) True statement: pure water is neutral on the pH scale. But tap water? That might be slightly acidic or basic depending on where you live. So don’t trust tap water—it’s a liar. A very useful liar.

Also, water is a fantastic conductor of electricity when it has impurities (like salt). But pure water is actually an insulator. So if someone tells you “water conducts electricity,” you can correct them: “Only dirty water does, you clean freak.” (Please don’t stick a toaster in your bath. That’s still a terrible idea.)
