How many moles of gas are present at a pressure of 1.00 atm in a container that is 4.0 liters in a room that is 25°C? A) 0.013 mol
B) 1.9 mol
C) 0.16 mol
D) 6.1 mol

One mole of gas is in a 2.0 L container at 1.0 atm pressure and 20°C. If the volume is doubled, and the temperature remains constant, what will happen to the pressure?
A) The pressure will quadruple.
B) The pressure will double.
C) The pressure will decrease by half. D) The pressure will decrease by one-quarter.
​

A) 0.013 mol

Explanation:

B) The pressure will double.

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.
