A spherical ball is dropped in a long column of a highly viscous liquid. The curve in the graph shown, which represents the speed of the ball (v) as a function of time (t) is

The temperature at which the molar specific volumes for liquid and vapor phases become equal is termed as:

A liquid drop acquires spherical shape due to:

​The diameter of a capillary is 4mm. If Reynolds's number of the tube is 1000 and the co-efficient of viscosity for the water is 0.02 poise, determine the maximum speed of water for the stream line flow in the tube?​

The coefficient of volume expansion of glycerine is $$49×10^{-5}\text{K}^{-1}$$​. Find the fractional change in its density for a 20° C rise in temperature?
