Text Solution

Verified by Experts
The correct answer is:
A

Surface tension arises due to extra energy of the molecules at the molecules at the surface

as compared at the interior of a liquid. The coefficient of viscosity for a liquid decreases with rise in temperature where as it increases for gases with increase in temperature. The flow is turbulent for a Reynold's number greater than 2000. Stream lines never intersect in a steady flow.
