?1.丙烷的沸點是指在標準大氣壓下，丙烷從液態轉變為氣態所需要的溫度。它的沸點通常被定義為-42.1℃，但實際上它的沸點會隨著環境壓力和純度的不同而有所變化。

2.丙烷的沸點與溫度有著密切的關系。一般來說，溫度越高，丙烷分子運動速度越快，分子間相互作用力減弱，從而更容易脫離液態轉變為氣態。因此，在較高的溫度下，丙烷的沸點會相應地升高。

3.丙烷是一種無色、無味、易燃的氣體，在工業生產和日常生活中都有廣泛應用。它可以作為燃料用于采暖、爐具等方面，也可以作為原料用于合成化學品。由于其易于儲存和運輸，并且對環境無污染，因此受到了廣泛關注。

4.例句1：在標準大氣壓下，丙烷的沸點約為-42℃。

例句2：隨著溫度升高，丙烷的沸點也會相應地提高。

例句3：工業生產中常用丙烷作為燃料進行加熱。

例句4：丙烷的沸點與環境壓力和純度有關，需要根據具體情況進行調整。

例句5：在低溫下，丙烷可以被壓縮成液態，方便儲存和運輸。

5.組詞：液化丙烷、丙烷氣體、丙烷分子、丙烷氣壓、丙烷溫度、標準大氣壓、純度。

6.Propane Boiling Point and Its Relationship with Temperature

Propane, also known as C3H8, is a colorless, odorless, highly flammable gas that is widely used in industrial production and daily life. As a dictionary editor, I will explain the boiling point of propane and its relationship with temperature in different styles to avoid AI detection.

The boiling point of propane refers to the temperature at which it changes from liquid to gas under standard atmospheric pressure. It is commonly defined as -42.1℃, but it can vary depending on environmental pressure and purity.

The relationship between propane boiling point and temperature is closely related. Generally speaking, as the temperature increases, the speed of propane molecule movement increases and the intermolecular interaction force decreases. This makes it easier for molecules to break away from liquid state and transform into gas state. Therefore, at higher temperatures, the boiling point of propane will also increase accordingly.

Propane is widely used as a fuel for heating, stoves, and other applications in industrial production and daily life due to its colorless, odorless, and highly flammable properties. It can also be used as a raw material for the synthesis of chemicals. Due to its easy storage and transportation, as well as its environmental friendliness, propane has received widespread attention.

Example sentences:

1. The boiling point of propane is approximately -42℃ under standard atmospheric pressure.

2. As the temperature increases, the boiling point of propane also increases accordingly.

3. Propane is commonly used as a fuel in industrial production for heating purposes.

4. The boiling point of propane is affected by environmental pressure and purity, and needs to be adjusted according to specific conditions.

5. Propane can be compressed into liquid state at low temperatures for convenient storage and transportation.

Word combinations: liquefied propane, propane gas, propane molecule, propane gas pressure, propane temperature, standard atmospheric pressure, purity.

In summary, the boiling point of propane is closely related to temperature and can vary depending on environmental pressure and purity. As a widely used gas in various industries and daily life, understanding its characteristics is essential for safe use.
