Heating a gas increases its kinetic energy, causing its molecules to move faster and collide more frequently. This increased collision frequency leads to greater internal friction and higher viscosity in the gas. Cooling a gas has the opposite effect, reducing molecular motion and collision frequency, thus lowering its viscosity.
Not all metals do, and it depends on the rate at which the metal is cooled. Basically, in some metals the crystal pattern in the metal changes when heated- and if rapidly cooled, that pattern is sort of "locked in" to the metal. If that locked in pattern is harder or more brittle than the earlier state, the metal has become more brittle. However, heating and then SLOW cooling can make some metals less brittle- it is called annealing.
No, basaltic lavas are typically hotter and less viscous than andesite lavas. Basaltic lavas have lower silica content, which results in their lower viscosity and ability to flow more easily. Andesite lavas, on the other hand, have higher silica content and are more viscous.

No, kerosene is not more viscous than bitumen. Kerosene is a low-viscosity liquid, typically used as a fuel, while bitumen is a highly viscous, thick substance often used in road construction and roofing. The viscosity of bitumen can be many orders of magnitude higher than that of kerosene, making it much more resistant to flow.
When magma is being heated it rises. When it is cooled, it sinks.
Because they are more hollow.
Water is more viscous than methylated spirits, and vegetable oils are more viscous than water.
because..................................................................................................................... density of heated gas is lower than cooled gas.
Volume is affected. For example, gases require more volume at higher temperatures than lower ones.
Toothpaste is more viscous because it flows less freely than milk.
the intermolecular attractionsis account for this behaivour of honey.

Blood viscosity is a measure of overall blood thickness. Therefore, there is no one place in the body where blood is more viscous than others. However, factors such as cholesterol, smoking, or some illnesses your blood may be more viscous than normal.

Added heat. Warm petroleum is far less viscous than cold. Pumps like water.
