A typical barometric pressure in Kansas City is 740 torr. What is this pressure in atmospheres, in millimeters of mercury, and in kilopascals?

Explanation:

Given parameters:

The barometric pressure in Kansas City  = 740torr

 Convert to mmHg, atm and kPa;

Now;

            1 atm  = 1torr

So;

          740torr = 740atm

Then;

        1 mmHg  = 1 torr

     740torr will also be 740mmHg

In kPa;

           1 atm  = 101325Pa

          740 atm  = 740 x 101325  = 74980500Pa;

  To kPa; divide by 1000

              74980.5kPa

both adhesion and cohesion are attractions.

they are different in that adhesion is the force of attraction between the molecules of two different substances, whereas cohesion is the force of attraction between molecules of the same substance.

possible examples include capillary action, in which the adhesion between water and glass causes the water to rise in a narrow tube against the force of gravity.

because of hydrogen bonding, water is extremely cohesive.

this causes molecules on the surface of water to be drawn inward, which is why drops of water form beads on smooth surfaces.
