At the proximal end of capillary, you get the fluid out in the tissue fluid due to blood pressure. At the distal end of the capillary, you get back the tissue fluid due to oncotic pressure of the blood proteins.

What is the attraction between substances of the same kind?

The attraction between substances of the same kind is called cohesion. It is due to intermolecular forces such as hydrogen bonding or Van der Waals forces, which cause the molecules to be attracted to each other. Cohesion is responsible for phenomena like surface tension in water.


What holds gas in a science lab?

In chemistry, substances are defined as three basic types. Solids, liquids, and gases. Each of these substances contain molecules. So, the difference between these types of substances is the intermolecular forces of attraction between these molecules. Substances with strong intermolecular forces of attraction tend to be solids, and substances with weak I.M.F.A.s are either liquids or gases. The difference between a gas and a liquid is that gas molecules move freely with weak I.M.F.A.s. So, liquid has molecules with stronger I.M.F.A.s, and therefore it retains its shape.


Why are two nonpolar substances able to dissolve in each other?

Two non-polar substances share similar attractive forces in their molecules, which is what enables them to dissolve in each other. The dissolving medium in a solution is referred to as a solvent.


What are the four forces of biological evolution?

The four forces of biological evolution are mutation, gene flow, genetic drift, and natural selection. Mutation introduces new genetic variations, gene flow allows the exchange of genes between populations, genetic drift is the random change in gene frequencies within a population, and natural selection favors individuals with traits that increase their chances of survival and reproduction.


3. Some forces act at a distance and thus do not require .?

Some forces act at a distance and thus do not require direct contact between objects. Examples include gravitational and electromagnetic forces. These forces can influence objects without physical contact due to their field-like nature.

What is the difference between adhesive and cohesive forces in materials?

Adhesive forces are the attraction between different substances, while cohesive forces are the attraction between molecules of the same substance.


What are valence forces?

Valence forces refer to the attractive and repulsive forces that act between atoms to form chemical bonds. These forces include ionic, covalent, and metallic bonding interactions that help hold atoms together in molecules or crystal structures. Valence forces determine the physical and chemical properties of substances.

Do all substances experience London dispersion forces of attraction between particles?

Yes, all substances experience London dispersion forces of attraction between particles to some extent. These forces arise from temporary fluctuations in electron distribution and are the weakest type of intermolecular force.


What are substances that are held together by physical forces not chemical?

Substances held together by physical forces include mixtures, colloids, and suspensions. These types of substances involve components that are physically blended or dispersed together, rather than chemically bonded. The interactions between the components are mainly due to forces such as van der Waals forces, hydrogen bonding, or electrostatic interactions.


What is the role of exchange particles do in an interaction?

Exchange particles mediate the interactions between particles by carrying forces between them. For example, photons mediate the electromagnetic force between charged particles and gluons mediate the strong nuclear force between quarks. Exchange particles are responsible for transmitting the fundamental forces of nature that govern the behavior of particles at a quantum level.


What are some forces that affect trading in global markets?

Currency exchange rates, geopolitical events, government policies and regulations, supply and demand dynamics, and market sentiment are all forces that can affect trading in global markets. These factors can influence stock prices, commodity prices, and overall market volatility.


What is the difference between cohesive and adhesive forces in materials?

Cohesive forces are the attraction between molecules of the same substance, while adhesive forces are the attraction between molecules of different substances. In materials, cohesive forces hold the molecules of the material together, while adhesive forces allow the material to stick to other surfaces.


If body A and body B are both within a system can forces between them affect the acceleration of the system?

Yes, if body A and body B interact with each other through forces, these forces can affect the net acceleration of the entire system. The net acceleration of the system is determined by the external forces acting on the system and the forces between the bodies within the system.


Contrast ionioc and molecular substances in terms of the types of attractive forces that govern their behavior?

Ionic substances are held together by electrostatic forces of attraction between positively and negatively charged ions, while molecular substances are held together by various types of intermolecular forces such as hydrogen bonding, dipole-dipole interactions, and London dispersion forces. Ionic substances have higher melting and boiling points due to the strong electrostatic forces, while molecular substances typically have lower melting and boiling points as the intermolecular forces are weaker.
