An experiment is carried out to determine the percentage composition by mass of sand and copper (II) sulphate in a mixture. A 10.0 g portion of the mixture is stirred in 200 cm3 of distilled water, until no further change takes place. The resulting mixture is filtered into a clean beaker using a funnel fitted with filter paper.

The diagrams to the right show the distribution and arrangement of gas particles in two different containers. according to kinetic-molecular theory, which of the following statements is true? check all that apply. if the temperatures of both containers are equal, container a has greater pressure than container b. if the volume of container a decreased, its pressure would decrease. if the pressure in both containers is equal, container a has a lower temperature than container b.
