Wind speed and air temperature are used to calculate a windchill factor.
<u>Explanation:</u>
<u></u>
Wind-chill factor is the reduction of body temperature due to the passing flow of lower-temperature air.
The air temperature value is always higher than the wind chill numbers. the heat index will be used if the apparent temperature is higher than the air temperature.So, Wind speed and air temperature are mainly used to calculate a windchill factor.
There are many ways, the surface loses its heat through conduction, evaporation,radiation, and convection.The rate of convection depends on the difference in temperature between the surface and the fluid surrounding the surface and the velocity of that fluid with respect to the surface. The air around the warm surface will be heated, an insulating layer of warm air forms against the surface.The layer becomes a boundary between two. As the wind speed is high the surface cools down rapidly.
Answer:
The answer is given in the attachment
Explanation:
Answer:
The water releases energy which causes the water molecules to have less kinetic and potential energy, changing their configuration from liquid to solid.
Explanation:
The conversion of water to ice is a phase change from liquid to solid. There is no chemical action taking place in this process just the state of matter taking up a new form.
- This phase change is called freezing.
- In freezing, the liquid water loses energy to the surroundings.
- By so doing, the water molecules have lesser energy
- The then take up fixed position within the lattice.
- This changes the state to solid with a well - ordered arrangement.
