How does alcohol affect the body chemistry?

Alcohol is a depressant, meaning that it affects the brain’s level of chemicals that increase mood, like dopamine and serotonin. “Some people may feel a boost in mood while drinking in small amounts, too much alcohol consumption can lead to feelings of depression or anxiety the following day,” said Gregory. What are 3 things that … Read more

Why are pools and riffles important?

Pools are important because they can provide depth and still water. Riffles: An area of stream characterized by shallow depths with fast, turbulent water. The riffles are short segments of the stream where water flow is agitated by rocks. The rocky bottom provides protection from predators, food deposition and shelter. What is between a riffle … Read more

What is between a riffle and pool of area of a stream?

Runs come after pools and before riffles, where water is deep (like pools), and has fast flowing water (like riffles), and a uniform flow. You can see this for yourself at home. Why are pools and riffles important? Pools are important because they can provide depth and still water. Riffles: An area of stream characterized … Read more

Why is water and chemistry important to life?

Water is a liquid which allows the chemistry of life to take place. It is also a polar molecule which allows most other molecules to be dissolved. Because of this, we call water a “solvent”. Having such a good solvent as water is critical for the functions of life. What is the chemistry and biology … Read more

What is the chemistry and biology of water?

Water has a simple molecular structure. It is composed of one oxygen atom and two hydrogen atoms. Each hydrogen atom is covalently bonded to the oxygen via a shared pair of electrons. Why is water and chemistry important to life? Water is a liquid which allows the chemistry of life to take place. It is … Read more

How does capillary action allow water to move up a straw?

Capillary action depends on cohesion, the attraction between particles of the same substance, and adhesion, the attraction between particles of different substances. When adhesion is strong enough, it will overpower cohesion between water molecules, and water will move up a surface or through a surface. How does water affect capillary action? Adhesion of water to … Read more

What happens to water in a capillary tube?

Water rises inside the capillary tube due to adhesion between water molecules and the glass walls of the capillary tube. This adhesion, together with surface tension in the water, produces an effect called capillarity , with a characteristic concave surface. How does water affect capillary action? Adhesion of water to the walls of a vessel … Read more

How does water affect capillary action?

Adhesion of water to the walls of a vessel will cause an upward force on the liquid at the edges and result in a meniscus which turns upward. The surface tension acts to hold the surface intact. Capillary action occurs when the adhesion to the walls is stronger than the cohesive forces between the liquid … Read more

How do you use a separating funnel in chemistry?

What is a separatory funnel used for in organic chemistry? Separating funnels are used for carrying out solvent extractions in organic chemistry. How does a separatory funnel work? A separatory funnel (sep funnel) is used to separate immiscible liquids. When two immiscible liquids are placed in a separatory funnel, two layers are seen. The denser … Read more

How does a separatory funnel work?

A separatory funnel (sep funnel) is used to separate immiscible liquids. When two immiscible liquids are placed in a separatory funnel, two layers are seen. The denser solvent will be the bottom layer. Most halogenated solvents are denser than water, most non-halogenated solvents are less dense than water. What is a separatory funnel used for … Read more
