What is the term used to describe the fluids tendency to resist flow?
Viscousity. The tendency for fluids to resist flow.
What is a liquid’s ability to flow?
An important physical property characterizing the flow of liquids is viscosity. Intuitively, viscosity describes the resistance of a liquid to flow. More technically, viscosity measures the resistance of a liquid to deformation at a given rate, such as when it is being sheared at finite velocity.
What causes fluids to resist flow?
Cohesive forces between like molecules are responsible for a liquid’s viscosity (resistance to flow) and surface tension (elasticity of a liquid surface).
Is the tendency for a fluid to resist flow?
Viscosity is the tendency for fluids to resist flow.
What characteristic allows organisms to resist changes in their own body temperatures?
All (or almost all) organisms have mostly water in their bodies allowing them to resist changes in their own temperatures. What does it mean that water is the “Universal Solvent”? It is called the “Universal Solvent” because water dissolves almost everything.
What determines a gas’s volume?
The volume of a gas is determined by the volume of the container it is in. Gases take the shape of their container and the volume of the container….
What is the property of the materials resistance to flow?
The intrinsic property of materials to resist the flow of electric current is called resistivity.
Is the tendency for fluids to resist flow water is more viscous than warmer water allowing floating organisms to use less energy to keep from sinking?
Viscosity is the tendency for fluids to resist flow. Cooler water is more viscous than warmer water, allowing floating organisms to use less energy to keep from sinking.
The viscosity of a liquid is a measure of its resistance to flow.
Which of the following is the tendency of a water molecule to stick to other water molecules?
cohesion
The tendency for water molecules to form weak bonds and stick to each other is called cohesion. Because of cohesion, water molecules remain joined together as they move within or between the cells of organisms.
Is the tendency within a body to resist flow?
How does water resist changes in temperature quizlet?
Water resist temperature change because of high specific heat which in turn helps our body (made up of 70 percent water) to keep the water from overheating or freezing just because the temperature changes. Temperature drops, molecules come together to make a solid (ice for water).
Which is a measure of a fluid’s resistance to flow?
Viscosity is a measure of a fluid’s resistance to flow. describes the internal friction of a moving fluid. A fluidwith large viscosity resists motion because its molecular makeup gives it a lot of internal friction. A fluid with low viscosity flows easily because its
Why does a fluid with large viscosity resist motion?
A fluidwith large viscosity resists motion because its molecular makeup gives it a lot of internal friction. A fluid with low viscosity flows easily because its molecular makeup results in very little friction when it is in motion.
How is the viscosity of a fluid measured?
Generally, the higher a fluid’s viscosity, the lower the fluid flow rate (other factors remaining constant). Viscosity is measured in units of centipoise. Another type of viscosity, called kinematic viscosity, is measured in units of centistokes. It is obtained by dividing centipoise by the fluid’s specific gravity.
How is the flow rate of a liquid measured?
There is now a wide variety of methods available to measure the flow of liquids, solids, gases and vapours. The actual velocity of the fluid at a given point (measured in metres per second). The volume rate of flow (measured in metres cubed per minute).
