Question

The air temperature and the velocity of the air have different values at different places in the earth’s atmosphere. Is the air velocity a vector field? Why or why not? Is the air temperature a vector field? Again, why or why not? 

Answer 1

Air temperature is a vector field because it have different magnitude in different points of space. Velocity of sound is a scalar (although canned velocity) because it depends on the temperature at the given point of space.
