Why cold water feels colder than air at the same temperature?

Density is the answer. Water is denser than air and the human body loses heat 25 times quicker while in water than it does in air, even though we’re talking about the same temperatures.

Because of density, water has a high specific capacity. Therefore, it takes longer to raise its temperature even a little, and it’s remarkable at retaining heat or cold. This explains why it takes so long until the hot soup cools down and why the ocean is colder than land. Additionally, water is an amazing conductor and it’s very effective at transferring that heat or cold to your body.

 

Polishing shoes and filling in a road’s potholes is pretty much the same thing.

You might find leather uninteresting just because it’s covered in teeny-tiny holes and scratches that spread when the light hits the material. Therefore, when polishing a leather shoe you add a thin layer of wax to it, filling in the holes and scratches just like a road crew repairs a street by filling its potholes. This process will also make the shoe look shinier when it hits the light.

 

Did you know that baby’s bodies contain more water than adults’?
