Are there any seamless winter gloves?

You use wool gloves to protect your hands from the cold and snow during the winter.?

• One day you spill some water on your gloves but decide they should still be suitable for use even though they are wet. To your surprise, the gloves do not protect your hands and you end up getting frostbite on your fingers. The fact that the wet gloves make your hand colder indicates that water is a better conductor than wool; the water conducts the heat away from your hands so they feel colder. True Or False?

• Answer:

  Very partly true but mostly false. Yes, the greater the density of the water, the more heat will be led out but the mean point is that, as water evaporates, it cools down because evaporation requires to take latent heat. This is, incidentally, the reason we sweat; its evaporation cools down our skin. However it requires that the air is not entirely saturated, i.e. the relative humidity is less that 100 percent. To prove it, try this: go with wet gloves in the fog and notice that it doesn't feel colder than usual. For information, the opposite, the condensation of water, creates latent heat and that is why the bad weather occurs because when moist and warm air rises, forming clouds, it keeps rising as the adiabatic cooling beyond the dew point temperature, releases latent heat, thus keeping the air rising and lowering even more the atmospheric pressure.
