Water is heavier than airbecause it is DENSER. This means that more water molecules are packed into a given volume. What does air and water tight mean? Air-tight means air can't get through(at least not very quickly). Water-tight means water can't get through. These qualities aren't ...
Is house gas heavier than air? Natural gas is always lighter than air, and will rise in a room if allowed to escape from a burner or leaking fitting. On the contrary,propane is heavier than airand will settle in a basement or other low level. Incomplete combustion can occur when the ga...

The vapor and liquid may cause burns. Vapors are heavier than air. Chlorotrimethylsilane reacts vigorously and exothermically with water to produce hydrogen chloride. Uses Chlorotrimethylsilane is a typical Silane Blocking Agent, which can protect or deprotect functional groups selectively. It is ...
Flammable vapor and air can form explosive mixture. In case of fire or high heat, combustion and explosion will occur. It can vigorously react with oxidants. It is easy to produce and accumulate static electricity when flowing too fast. The vapor is heavier than air and can spread to conside...
Butane is an extremely flammable substance and should be kept from exposure to heat and flame. The gas is heavier than air, and distant ignition is possible as it travels near the ground. The use of butane certainly does not come without health and environmental risks. ...
答案在第一段最后一句,Clouds formed by the vapor ensure that water falls back down to Earth as rain,sleet,snow or hail.(水汽形成的云团导致降水并以雨,雨夹雪,雪,或者冰雹的形式重新回到地球。)3.【答案】Water is probably the most precious resource on the Earth. We should try our best to ...
The newly-formed ice crystal (snowflake) is heavier than the surrounding air and it begins falling. As it falls towards Earth through humid air, more water vapor freezes onto the surface of the tiny crystal. This freezing process is very systematic. The water molecules of the vapor arrange ...
Such an increase in solar energy will introduce Earth to a whole new kind of global warming. The polar ice caps will melt and the atmosphere will fill with water vapor that traps even more heat. By one or two billion years from now, temperatures will have risen so much that the oceans ...
Most vapors are heavier than air. They will spread along ground and collect in low or confined areas (sewers, basements, tanks). Vapors may travel to source of ignition and flash back. Substance will react with water (some violently) releasing flammable, toxic or corrosive gases and runoff....
