Q1: Kinematic viscosity of water as compared to that of air is

ANS:D - 15% less

The kinematic viscosity of water is 15% less compared to that of air. Explanation: Kinematic viscosity is the ratio of dynamic viscosity to density. It quantifies a fluid's resistance to flow under the influence of gravity. Water has a higher dynamic viscosity (resistance to flow) than air due to its molecular structure and greater molecular cohesion. However, water is significantly denser than air. When considering kinematic viscosity, which factors in density, the lower density of air results in a higher kinematic viscosity compared to water. Therefore, the kinematic viscosity of water is less than that of air.
