We can say that, lowering the temperature of the fuel will cause that it will come to its "pour Point" and starts to lose its ability to flow, the lowering the temperature more and more, this will cause the start of wax formation, once wax starts to form this is the "cloud Point". Lowering the temperature more and more will cause the whole fuel will crystallize and solidify this is the "Freezing Point". So, in case of the water, it becomes the same.

Freezing pt of water is 0°C and pour point of is also 0°C, we can say Pour point and freezing point is equal to water.

Freezing point:

The temperature at which a liquid turns into a solid when cooled.

The pour point of a liquid is the temperature at which it becomes semi solid and loses its flow characteristics. In crude oil a high pour point is generally associated with a high paraffin content, typically found in crude deriving from a larger proportion of plant material.

The definition of pour point is the temperature allow the fluid go through pipeline. So how it can be equal in water case?
