Is it possible to turn liquid into vapour without heating
Answers
Answer: No, I don't think so that liquid can into vapour without heating because if we use electricity instead of flame then also the heat takes place.
Answer:
You can boil water at room temperature without heating it. This is because boiling is about pressure, not just temperature. Here's an easy way to see this for yourself.
Explanation:
The boiling point of water or any other liquid depends on vapor pressure. As you lower the pressure, the boiling point of the water drops. You can see this if you compare the boiling point of water at sea level with the boiling point of water on a mountain. The water on the mountain boils at a lower temperature, which is why you see high-altitude instructions on baking recipes!
When you pull back on the plunger, you increase the amount of volume inside the syringe. However, the contents of the syringe can't change because you have sealed it. The air inside the tube acts as gases do and the molecules spread out to fill the whole space. The atmospheric pressure inside the syringe drops, creating a partial vacuum. The vapor pressure of the water becomes high enough compared to the atmospheric pressure that the water molecules can easily pass from the liquid phase into the vapor phase. This is boiling.
