There are four important warning signs that should prompt you to talk to a health care provider. 1  Pain. Pain from arthritis can be constant or it may come and go. 2  Swelling. Some types of arthritis cause the skin over the affected joint to become red and swollen, feeling warm to the touch. 3  Stiffness.
There's a whole lot of water on Earth! Something like 326,000,000,000,000,000,000 gallons (326 million trillion gallons) of the stuff (roughly 1,260,000,000,000,000,000,000 liters) can be found on our planet. This water is in a constant cycle -- it evaporates from the ocean, travels through the air, rains down on the land and then flows back to the ocean.
Each gallon of sea water contains about 4.5 ounces of salt, which is about 3.5 percent of its total weight. Almost all of the other answers here were correct (with varying degrees of precision) but essentially said that water weighs (for a US gallon) 8.34 pounds so multiply by 5 and your answer is lbs.
