Ten grams of a gas occupies 12.5 liters at a pressure of 42.0 cm hg. what is the volume when the pressure has increased to 75.0 cm hg? 6.00 l 7.00 l 8.00 l none of the above

             7.0 L

              According to Boyle's Law, " The Volume of a given mass of gas at constant temperature is inversely proportinal to the applied Pressure". Mathematically, the initial and final states of gas are given as,

                                     P₁ V₁  =  P₂ V₂     (1)

Data Given;

                  P₁  =  42.0 cm Hg

                  V₁  =  12.5 L

                  P₂  =  75.0 cm Hg

                  V₂  =  ??

Solving equation 1 for V₂,

                   V₂  =  P₁ V₁ / P₂

Putting values,

                   V₂  =  (42.0 cm Hg × 12.5 L) ÷ 75.0 cm Hg

                   V₂  =  7.0 L

          As the Pressure has increased from 42.0 cm Hg to 75.0 cm Hg, therefore, Volume got decreased from 12.5 L to 7.0 L.

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.
