Mass<span> is the amount of matter in an object. Move to a different planet and an object's weight will change, but its </span>mass<span> will be the same. </span>
The correct answer is suspensions only. The suspension is a heterogeneous mixture that contains solid particles that are largely enough to undergo sedimentation. Usually, these particles are about one micrometer which makes these solute to be very easy to be free from their solvent and be filtered.

Answer: option B. The kinetic energy of gas molecules is directly proportional to the Kelvin temperature of the gas.
Explanation:
The kinetic theory of gases explains the behavior and properties of gases from a molecular perspective.
Specifically and explicity, the kinetic theory of gases states that gases are constituted by particles (molecules) and that the average kinetic energy of the particles is proportional to the absolute temperature (Kelvin scale) of the gas. Furthermore, the temperature of all the (ideal) gases is the same at a given temperature.
Hence, you know that the higher the temperature of the gas, the higher the kinetic energy and the average speed of the molecules.
Other postulates of the kinetic theory of gases are that: i) the volume of the particles is neglectible; ii) the particles do not exhibit intermolecular attraction or repulsion; iii) the particles are in continuous random motion in straight paths, until they collide with other particles or the walls of the vessel, and iv) the collisions are elastic (the energy is conserved).
