液化ガスと気化ガスの違いは何ですか?
What is the difference between liquified gas and vaporized gas?

エアゾール商品には、原液(内容液)を溶解させ吐出させるために噴射剤(ガス)が使われます。この中に、圧力をかけて液体とした噴射剤を使用するタイプがあり、このガスを液化ガスと呼びます。容器内は噴射剤の圧力で加圧状態になっています。ガスは缶内で原液と液化ガスが均一に溶解した液相部と噴射剤が蒸気となっている気相部に分かれます。気相部に気体として存在しているものを気化ガスと呼びます。

In aerosol products, a propellant is used to dissolve and discharge the contents, and certain types of propellants are liquified by compression. Such liquified propellants are called as liquified gas. Therefore, the contents in a can are under pressure due to the pressure of this propellant. In a can, gas is divided into two phases; the liquid phase which consists of evenly dissolved contents and liquified gas; and the vapor phase which consists of vaporized propellant. What exists in the vapor phase in the form of gas is called vaporized gas.
