Explanation:

The viscosity of liquids is affected by temperature. For example, trying to pump certain slurries using more energy can cause the apparent viscosity to increase. This in turn causes the slurry to exhibit more resistance and can actually reduce the flowrate—even though more energy is used. While liquid density generally decreases with increasing temperature, this is not always the case.
