1.	Explain the term .laminar flow.. Is the velocity of molecules same in all the layers in laminar flow ? Explain your answer.
Answer» Solution :When a liquid flows over a fixed surface, the LAYER of molecules are stationary. As the distance of layers from the fixed layer increases, the VELOCITY of the upper layers increases. This type of FLOW in which there is a regular gradation of velocity in PASSING from one layer to the next is called laminar flow. In laminar flow, the velocity of molecules is not same in all the layers because every layer offers some resistance or friction to the layer immediately below it.
