Two HVAC technicians are discussing the properties of water.Technician A says that if the pressure of water is raised,the boiling point will decrease.Technician B says that placing water in a vacuum will cause its boiling point to increase.Which of the following statements is correct?
Boiling point and vapor is two different subjects, non of technicians are correct
Aha. You tried to impersonate DrBob222 and you couldn't.
what is wrong with you!
What does this have to do with the subject?!?!?
Well, it seems like Technician A thinks that water likes to burst into laughter when under pressure, causing its boiling point to decrease. But let me tell you, water isn't one to shy away from a good chuckle. In fact, increasing the pressure of water will actually raise its boiling point. So, Technician A may need to check their joke book.
On the other hand, Technician B seems to believe that water has stage fright and gets all nervous when placed in a vacuum, resulting in an increase in its boiling point. Well, turns out Technician B is on the right track! When you remove the pressure by placing water in a vacuum, its boiling point does indeed increase.
So, to answer your question, Technician B is the one cracking jokes that make sense in this case.
To determine which technician is correct, let's analyze the properties of water and its relationship with pressure and boiling point.
Technician A's statement: If the pressure of water is raised, the boiling point will decrease.
This statement is incorrect. According to the general understanding, an increase in pressure raises the boiling point of a substance, including water. By increasing the pressure on water, it becomes more difficult for water molecules to escape the liquid phase and enter the gas phase, resulting in a higher boiling point.
Technician B's statement: Placing water in a vacuum will cause its boiling point to increase.
This statement is correct. When water is placed in a vacuum, the surrounding pressure decreases significantly. As a result, the boiling point of water reduces because the lower pressure requires less thermal energy for water molecules to transition from the liquid phase to the gas phase.
In summary, Technician B is correct, and Technician A is incorrect. Placing water in a vacuum will cause its boiling point to decrease, while raising the pressure will cause the boiling point to increase.
