Question
Which of the following statements are true about creaming? More than one answer.
The rate of creaming decreases with increase in temperature
The rate of creaming increases with increase in temperature
The zero shear viscosity of cream decreases with time if the cream is stable
The zero shear viscosity of cream decreases with time if the cream is unstable
The cohesive energy of cream decreases over time if cream is unstable
The rate of creaming decreases with increase in temperature
The rate of creaming increases with increase in temperature
The zero shear viscosity of cream decreases with time if the cream is stable
The zero shear viscosity of cream decreases with time if the cream is unstable
The cohesive energy of cream decreases over time if cream is unstable
Explanation / Answer
The rate of creaming decreases with increase in temperature as the extra energy provided by the increased Temperature imparts more vibrational energy to the particles and hence increases there collision frequency. Now due to this extra energy, the interactions at the molecular level will be disturbed hence the creaming process will be hindered.
The shear viscosity of cream decreases with the increase in temperature if a cream is stable.
But if the cream is stable and the temperature is almost constant then the zero shear viscosity should not decrease with time.
