Vedclass · Answer

(B) The viscosity of a fluid is a measure of its resistance to flow. For liquids,the viscosity is primarily due to cohesive forces between molecules. As temperature increases,the kinetic energy of the molecules increases,which overcomes these cohesive forces,causing the viscosity of liquids to decrease. For gases,the viscosity is primarily due to the transfer of momentum between layers of gas molecules due to random thermal motion. As temperature increases,the random motion of gas molecules increases,leading to more frequent collisions and a higher rate of momentum transfer,which causes the viscosity of gases to increase. Therefore,when the temperature increases,the viscosity of gases increases and the viscosity of liquids decreases.
