increases
decreases
remains same
first increses then decreases

abhisar · Answer

Viscosity decrease with increase in temperature

anonymous · Answer

can u explain the reason too plz?

anonymous · Answer

@aaronq

aaronq · Answer

because intermolecular forces are weakened by stronger thermal vibrations as temp rises.

anonymous · Answer

yes...decreases throughly when you increse the temp.the motion of molecules in the liquid got faster and hence friction between layers decreases and hence viscosity decreses.!

anonymous · Answer

in solids wen we incearse temp collison between atoms or particles increses hence incresing frictional force ...
y dont this happen in liquid

anonymous · Answer

it exist in liquids but in solids not the collision increases but the amplitued of vibration of atoms ot ions increases..!!

anonymous · Answer

oh yes i got it thanku

anonymous · Answer

you welcome ddear sis.

anonymous · Answer

and that is why volume of solid inrease on incresing the temp or why things got greater volume in summer than in winter..
