On the relationship between the boiling point of ethyl acetate and the pressure
The properties of human substances often change with the situation, among which the boiling point of ethyl acetate and the pressure are closely related. Although Xi Xian did not elaborate on this object, the principles of physics are the same in ancient and modern times.

It is natural to observe that the difference in pressure affects the change of various objects. In a closed vessel, the pressure is increased or decreased, and the boiling point of the object is also changed accordingly. Ethyl acetate has a special property. Its boiling point is under the ordinary pressure, and there is a fixed number. However, if the pressure changes, the boiling point will fluctuate accordingly.

When the cap pressure increases, the binding between molecules increases. If the molecule wants to escape into a gaseous state, more energy is required, so the boiling point rises; on the contrary, when the pressure decreases, the binding of the molecule weakens, and it is easier to leave the liquid phase, and the boiling point decreases.

Try to verify it with real evidence. Prepare a sophisticated instrument, measure an appropriate amount of ethyl acetate, and place it in a device with controllable pressure. First set a constant pressure, measure its boiling point, and record its value. Then gradually increase the pressure, and then measure the boiling point, and see its value increase; and gradually reduce the pressure, and then measure it again, and the boiling point decreases.

It can be seen from this that the boiling point and pressure of ethyl acetate are actually restricted by each other. In the field of chemical industry and scientific research, only by understanding this principle can we make good use of its properties and make profits for all things. Although the ancients did not specifically talk about this principle, today's research and pursuit of people have also inherited the spirit of the predecessors to explore nature, so as to clarify physics and benefit the world.
