As temperature increases, base oil density typically decreases. This is due to the thermal expansion of the oil molecules, causing them to spread out and occupy a larger volume, resulting in lower density. Conversely, as temperature decreases, base oil density tends to increase.
The frequency of collisions is reduced
If you have 100 kilos of oil in a sealed can and you cool it or warm it, the weight of the oil will not change. However the volume of the oil in the can will change.
Temperature measures the speed of random thermal motion on the atomic and molecular level. When sub-microscopic particles are moving faster, the liquid as a whole will be more fluid and less viscous.
Yes. If the temperature changes enough, the viscosity of oil will change, too. Oil is designed to resist changes in viscosity with temperature changes, at least to a degree. But if the change (either hotter or colder) is extreme, then the viscocity will most certainly change. And, as you'd expect, as it gets hotter, the viscosity of oil decreases (it get thinner), and as it gets colder, the viscosity of oil increases (it gets thicker).
The sample of water that has the lowest vapor pressure is the sample at a lower temperature. Vapor pressure decreases as temperature decreases because fewer molecules have enough energy to escape into the gas phase.

decreases as the temperature of the gas decreases. This relationship is explained by the ideal gas law, which states that pressure is inversely proportional to temperature when volume and amount of gas are constant.
The density of fuel oil decreases as temperature increases. This is because as temperature rises, the molecules in the fuel oil spread further apart, resulting in a decrease in density. Conversely, as temperature decreases, the molecules come closer together, leading to an increase in density.

As the temperature decreases, kinetic energy decreases, and particles slow down.
As the dew point temperature of a sample of air decreases, the amount of moisture in that air remains the same. The dew point temperature is the temperature at which air becomes saturated with moisture, so a lower dew point means the air is able to hold less moisture before reaching saturation. However, the actual amount of moisture in the air does not change as the dew point temperature changes.

the standard deviation of the sample decreases.
When temperature decreases, a fluid will eventually freeze and become solid
