Mass flow occurs due to difference in pressure across two points.
how electric charges flow in a wire due to potential difference across its two ends?
Assertion : Mass or bulk flow is the movement of substance en masse from one point to another, as a result of pressure difference between the two points.
Reason: It can be achieved only through positive hydrostatic pressure.
Answer the following questions in brief.
Mention atleast two conditions, when water movement occurs in plants due to root pressure.
