When the fluids temperature increases does the density decrease decrease?
Yes!
How does viscosity compare to density?
they are two truly different concepts. The density is a measurement of the molecular weight of the composition. In simpler words, density = number of molecules x molecular weight/volume occupied, while the viscosity is a measurement of the inter-molecular forces and molecule shapes. Viscosity tells you the "friction" between two layers of the given fluid, while density varies slightly with temperature, viscosity changes rapidly. Both density and viscosity decreases with temperature, but viscosity mostly has an exponential relationship with temperature. Density holds a linear relationship. This temperature viscosity relationship is the base of the auto lubricant technology. Viscosity and density are two different physical phenomena depending on totally different aspects. The common misconception of "heavier fluids are more viscos" is to be omitted.
The movement of substances within the body within body fluids is?
Circulation
What is the movement of the fluid called?
Convection is heat transfer by the movement of heated fluids. Heat transfer is the movement of energy from a warmer object to a cooler object.
Shifts the direction of free moving fluids such as air and water?

When the fluids temperature increases does the density decrease decrease?
Yes!
Do warm fluids have a lower density or a higher density?
The density of fluids decreases as temperature increases. This is because heat makes the particles in fluids move faster and spread farther apart, which means that there are fewer particles in a given volume.
Is there any mathematical relationship for the effect of temperature on hydrocarbon density?
With increase in temperature , the density of fluids decreases and their vapour pressure increases. There's no direct relationship for temp-density of HYdrocarbons. But temperature and density are inversely proportional and the constant of proportionality varies from fluid to fluid. For hydrocarbons that constant can be calculated keeping in mind its VP, boiling point at ambient conditions and its constituents.
How can temperature affect density in a liquid when temperature is decreasing?
Typically, a lower temperature denotes higher density, but many LIQUIDS are uncompressible (water actually expands slightly as it freezes) and therefore density in maintained. FLUIDS on the other hand encompass both liquids and gasses, of which gasses ARE compressible and will increase in density as temperature drops.
What is the movement of heated fluids called?
Convection is heat transfer by the movement of heated fluids. Heat transfer is the movement of energy from a warmer object to a cooler object.
Can fluids be measured in terms of density?
Yes
Is it true that heat transfer by the movement of currents within a fluid is called density?
No, it is not true that heat transfer by the movement of currents within a fluid is called density; it is actually called convection. Density is something else entirely, it refers to weight per a given volume. Of course, density is relevant to convection. Heat causes fluids to expand and therefore to become less dense, and therefore to rise.
Is density affected by temperature?
Yes, see the table for air.

What causes the transfer of thermal energy during convection?
The movement of matter during convection is what transfers thermal energy.The air or liquid currents help transferring thermal energy through convection as the currents of higher temperature are of less density (lighter) and move upwards while that of less temperature are of higher density (heavier) and move downwards.Convective heat transfer, often referred to simply as convection, is the transfer of heat from one place to another by the movement of fluids (liquids or gases). Convection is usually the dominant form of heat transfer in liquids and gases.
What is the effect of negative pressure in fluid flow?
The effect of negative pressure or vacuum, lowers the boiling point of fluids. Water will boil at room temperature in a vacuum. Automotive cooling systems are pressured to achieve the opposite result of raising the boiling temperature.
Which term for the vertical circular movements of fluids that transfer due to changes in density?
Convection currents are the vertical circular movements of fluids that transfer due to changes in density.
Transfer of heat by movement of fluids?
Convection.
