If the viscosity of the honey is tested at several different temperatures, the distance that the honey flows is the ____ variable and the temperature of the honey is the ____ variable. Which of the following answers is the correct variables for the two? A. dependent/independent B. independent/dependent C. independent/control D. dependent/control
The correct option is D. Because the distance that the honey flows is a dependent variable. Becuase the coefficient of viscosity is dependent on the velocity gradient (v/L). And, Viscosity is very temperature dependent • It decreases with increasing temperature (in case of liquids). But, Viscosity of a gas increases with increasing temperature.
