Substance B is found to be more viscous than substance A. This means that _____.

B flows faster at room temperature than A does
B flows slower at room temperature than A does
B has more mass per volume than A does
B has less mass per volume than A does

Respuesta :

"B flows slower at room temperature than A does." 

The right answer is B (the second option, B flows slower).

Viscosity can be defined as the set of phenomena of resistance to flow occurring in the mass of a material, for a uniform flow and without turbulence. The higher the viscosity, and the more easily the fluid's ability to flow, the greater the energy dissipated by the flow.
