    Heating the water after achieving 100°C will never increase its temperature due to phase change till the last drop of water evaporates. After all water converts into vapour, the temperature starts increasing. This is called Superheating.

    • @zebralearnings
      @zebralearnings  8 หลายเดือนก่อน +11

      Yes you are correct. By mistakenly I have explained in that way for the easy understanding. The water can't reach the temperature above the 100°C. Only the water vapor can reach more than 100°C. But, it will not affect the understanding of this topic.

    The water temperature remains constant and the water vapor is overheated. The flame should flow around the entire tank. The heated water will boil at a temperature of 100 °C and the flames flowing around the tank will additionally heat the water vapor to a higher temperature, e.g. 107 °C.

    • @leszekporeysky6441
      @leszekporeysky6441 ปีที่แล้ว

      I would show it on a potato fry. When we boil water in a kettle, we see "water vapor" rising. However, what we see is not water vapor, it is microscopic water droplets formed from water vapor that condensed on contact with cold air. This is because the steam was not superheated and was 100 °C. The situation is different when we prepare fries in a fryer. The oil is heated to a temperature of 120 °C (initially 190 °C). When we add French fries to the oil, the water contained in the fries begins to boil. The temperature of the fries in hot oil remains constant at 100°C, but the water vapor passing through the oil heats up to 120 degrees, which is why we do not see "water vapor" above the fryer, i.e. micro-droplets of water, because the water vapor was properly superheated. She had a reserve of energy that prevented it from immediately condensing.

    • @zebralearnings
      @zebralearnings  ปีที่แล้ว +2

      Yeah, that's you're correct. We can't heat the water more than 100°C. Once the water reached the 100°C temperature, it will start to change the phase from liquid to vapor and the vapor can reach more than 100°C temperature.
      And the flames should be around the tank. Because, in HVAC system the heating process happening around the coil. But for easy understand I made this animation like this.

      @@zebralearnings I thought so. A beginner in the profession only sees copper pipes, measures temperature and pressure, but does not see what phase the refrigerant is in a given section of the evaporator. Is it a gas? or liquid? It's like the structure of an atom. At school they taught me that electrons revolve around orbits like planets, although it has long been known that they have a wave-particle nature. They are a particle and a wave at the same time. However, this is difficult to understand.

      @@zebralearnings When it comes to particles and waves at the atomic level, I have already exhausted my understanding. We have three spatial dimensions and one temporal dimension. I understand spatial dimensions, but without understanding what time is, I will not be able to understand space-time. Therefore, I will not be able to understand what entropy is. But now I focus on simpler tasks. I am interested in systems in which you have one compressor and several evaporators operating at different temperatures. For example, imagine the evaporator of an air heat pump operating at a temperature of -7°C, the COP of the system is 2.5. What will happen when half of the evaporator is exposed to a temperature of +7°C? Will COP increase, remain unchanged or decrease.

    @dachee 8 หลายเดือนก่อน +6

    You cannot explain superheat and subcooling without mentioning the relationship of pressure, temperature and volume, ie. PV/T, Charles' Law. Example, Water and steam cannot have temperature above 100 degrees C at atmospheric pressure. To have higher than 100 degrees C, water and steam must be within a restricted volume that raises it's pressure, like a pressure cooker.

    • @zebralearnings
      @zebralearnings  8 หลายเดือนก่อน +3

      Let us be clear that pressure and temperature are important factors to be considered, for instance water boils at around 68 Degrees C on Mount Everest. Discussions are relevant. Lower the pressure on water surface and the boiling temperature of fluid will decrease. Change of state will commence at that temperature .To comprehend Superheat and Sub cooling within HVAC , It is important to know the manufacturer's design, and use the recommended method to calculate this phenomenon.

      Yes you are correct. At 100°C water will start to boil and change from liquid to vapor phase. But if we give temperature more than 100°C we can make sure the water is changing to vapor.
