The gas in the gas tank is used up. What's wrong with the water?
Oh ~ upstairs to say another reason. I know there's an explanation, the gas tank is used in high density gas compression, the compression of a substance needed to prevent gas in high density compression due to the expansion of the explosion of molecular collision friction, when the gas is exhausted, the substance is left in the bottle, hot and cold temperature and other factors after sublimation into liquid.
Gas Co in the filling, impurity bottle and bottle wall and with the oxide is cleared up, and the weight of material is relatively heavy, but no weight, from a certain extent against you as a consumer of power.
1 is the winter weather is cold, gas liquefaction occurs, when the temperature slightly increased, the liquid gas can also burn.
Normal phenomenon, but the water can be burned, so when dealing with the water to pay special attention to the gas bottle water is usually due to the two cases
