What is voltage in real life? A more concrete example of voltage from real life is a water tank with a hose extending from the bottom. Water in the tank represents stored charge. It takes work to fill the tank with water. The more water in the tank, the more pressure. The more charge stored […]
What are the 5 principles of the kinetic molecular theory of gases?
What are the 5 principles of the kinetic molecular theory of gases? The five main postulates of the KMT are as follows: (1) the particles in a gas are in constant, random motion, (2) the combined volume of the particles is negligible, (3) the particles exert no forces on one another, (4) any collisions between […]
How do humans withstand pressure?
How do humans withstand pressure? Answer 1: Our bodies are strong enough to resist the forces that compress us. A good analogy is blowing up a balloon. When the balloon is small even though the pressure of air inside the balloon exceeds the surrounding pressure, the strength of the elastic balloon is great enough to […]
What are 2 chemical properties?
What are 2 chemical properties? Examples of chemical properties include flammability, toxicity, acidity, reactivity (many types), and heat of combustion. Iron, for example, combines with oxygen in the presence of water to form rust; chromium does not oxidize (Figure 2). What is water physical properties? Physical properties Selected physical properties of water melting point 0.00 […]
Why is sodium chloride not poisonous?
Why is sodium chloride not poisonous? Salt water is full of sodium chloride molecules. are not poisonous and reactive like sodium metal and chlorine gas because they are electrically charged atoms called “ions.” The sodium atoms are missing their outer electron. Why does sodium chloride explode in water? Scientists who’ve also experimented with molten salt […]
Is chalk a precipitate?
Is chalk a precipitate? Composition: Chalk is a form of calcium carbonate, having the same chemical composition as ground calcium carbonate, limestone, marble, and precipitated calcium carbonate (PCC). In fact, all of the calcium carbonates listed in the previous sentence have the same crystal form, calcite. What is the purpose of the chalk lab? Purpose: […]
Why is maintaining a steady state important?
Why is maintaining a steady state important? A constant supply of energy is required for maintaining steady state, as maintaining a constant concentration of a molecule preserves internal order and thus is entropically unfavorable. When a cell dies and no longer utilizes energy, its internal composition will proceed toward equilibrium with its surroundings. How do […]
Why liquids can flow?
Why liquids can flow? Liquids flow because the intermolecular forces between molecules are weak enough to allow the molecules to move around relative to one another. In liquids, the intermolecular forces can shift between molecules and allow them to move past one another and flow. What do liquids flow? A liquid is made up of […]
Can balanced forces stop a moving body?
Are passenger side mirrors required?
Are passenger side mirrors required? There are a few states that require both side mirrors to be present and functional, but in most states, it is considered legal to drive with just one side mirror when it is complemented by a second one—like your rear view mirror. Some states require side mirrors if the rear […]
