What is the relationship between the temperature of a fluid and its viscosity?
As temperature increases, viscosity increases.
As temperature increases, viscosity decreases.
Temperature does not affect viscosity.
Viscosity is only affected by pressure, not temperature.
Which of the following best describes the effect of temperature on the density of a fluid?
Increasing temperature generally increases fluid density.
Increasing temperature generally decreases fluid density.
Temperature has no effect on fluid density.
Fluid density is only affected by pressure changes.
How does the temperature of a fluid affect its buoyancy?
Higher temperature decreases buoyancy.
Higher temperature increases buoyancy.
Temperature has no effect on buoyancy.
Buoyancy is only affected by the fluid's salinity.
What happens to the pressure of a fluid when its temperature is increased, assuming the volume remains constant?
Pressure decreases.
Pressure increases.
Pressure remains constant.
Pressure fluctuates unpredictably.
Which of the following statements is true about the thermal expansion of fluids?
Fluids contract when heated.
Fluids expand when heated.
Fluids neither expand nor contract when heated.
Fluids expand only when cooled.
In which state of matter do fluids exist?
Solid and liquid
Liquid and gas
Solid and gas
Liquid only
How does temperature affect the surface tension of a liquid?
It increases the surface tension
It decreases the surface tension
It does not affect the surface tension
It first increases then decreases the surface tension
What is the effect of temperature on the solubility of gases in liquids?
Solubility increases with increasing temperature.
Solubility decreases with increasing temperature.
Temperature has no effect on solubility.
Solubility is only affected by pressure.
Which of the following is true about the kinetic energy of fluid molecules as temperature increases?
Kinetic energy decreases.
Kinetic energy increases.
Kinetic energy remains constant.
Kinetic energy is not related to temperature.
How does temperature affect the rate of diffusion in fluids?
Higher temperature decreases the rate of diffusion.
Higher temperature increases the rate of diffusion.
Temperature has no effect on the rate of diffusion.
Diffusion rate is only affected by the fluid's viscosity.
When an object sinks that is ________________ buoyancy.
What is the surface tension of boiling water?
Zero
Infinity
