increased why? Explain. & how going
the velocity of the liquid without altering
the temperature
of liquid ?

to reduce​

Answer 1

Answer:

Temperature is increased.

1) As the temperature of a liquid increases,the movement of its molecule increases,which disturbs the imbalanced forces on the surface of liquid.thus the barrier of tightly bound molecules weakens thereby,Surface tension decreases.

2) As the temperature of a liquid increases,the energy of its molecules increases which increases the movement of molecules.so the liquid becomes more fluid.thus viscosity of liquid decreases.
