A smaple of gas occupies 10 m^3 at a pressure of 120kPa. if the volume of the sample is compressed to 3 m^3, what is the new pressure of the gas

Explanation:

The new pressure can be found by using the formula for Boyle's law which is

Since we are finding the new volume

From the question we have

We have the final answer as

Hope this helps you

in chemistry, adhesion and cohesion are attractive forces that exist between molecules. they hold the molecules together from each other. they are different in that adhesive force exists between molecules of different substance while cohesive force happens between molecules of same substance.

adhesion between water and glass causes water molecules at the edge of water and glass interface to climb up the wall in a narrow glass tube. this is called capillary action. cohesion is what gives glass its shape and causes water to form a droplet.
