A gas is heated to 80°C and has a pressure of 1350 mmHg. If the container expands to hold a volume of 800 mL, what was the volume of the gas, (in litres), at a temperature of 50°C and 900 mmHg pressure?

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.
