Relative humidity. There are many measurement standards.
Yes, the water bottle is leak-proof.
The sea serves as an endless supply of liquid water that evaporates and increases the humidity in the air just above it. In contrast, if you have a dry air mass in the middle of, say, Asia, there is no ready source of water that might evaporate and moisten the air.
Some of the best spill-proof water bottles on the market include Hydro Flask, CamelBak, and Contigo. These brands offer durable and leak-proof designs that are great for keeping your drinks secure on the go.
Ice Air is less dense than water, so water sinks below air. A rock is more dense than water, so it sinks in water and air. And helium, which is less dense than air, rises in air and in water.
Salt water has a higher density than both mineral water and air. Mineral water has a lower density than salt water but higher than air. Therefore, air has the lowest density among the three.
yes, it is water proof
yes they are water proof
One homely proof is a small "home handyman" compressor. All compressors have a valve in the bottom. After the compressor has been filled with ambient air, it is used for the job at hand, and then "bled" of the compressed air inside the tank. The last step is to open the valve on the tanks very bottom - and water will drip out. That water was in the air, and precipitated out when the air was compressed.
no rock is water proof if a rock get hit with water it does erode so no rock is water proof
The vast majority of plastics are water proof, they are rendered or made not water proof on purpose.
yes they are water proof

60% wbv. <><><> Depends on the proof (strength) of the Vodka. 80 proof IS 60% water, but 100 proof is 50% water.
