How Temperature Affects Viscosity:
Viscosity can be
defined as the internal friction that occurs as a material flow, relative to
itself. As a material's viscosity increases, its fluidity decreases.
Inversely, as its
viscosity decreases, its fluidity is said to increase.
The temperature
dependence of liquid viscosity is the phenomenon by which liquid viscosity
tends to decrease as temperature increases. As temperature
rises, a material will likely
become more fluid in nature, whereas a colder material will likely be more viscous.
The values shown to the
below, for instance, are subject to change based on the temperature at which
they are observed. The amount by which the
viscosity changes will
be based on the material. Here are some additional examples of how viscosity changes
with respect to temperature:
温度如何影响粘度：
粘度可以定义为作为材料流动发生的内部摩擦，相对于自身。随着材料粘度的增加，其流动性降低。
相反，随着其粘度降低，据说其流动性增加。
液体粘度的温度依赖性是液体粘度随温度升高而趋于降低的现象。温度上升，一种材料在自然界中可能会变得更加流动，而较冷的材料可能会更粘稠。
例如，下面显示的值可能会根据观察它们的温度而变化。
以下是粘度如何随温度变化的一些其他示例：
