What is a quantized value? Quantized: In quantum mechanics, the concept that a system cannot have any possible energy value but instead is limited to certain specific energy values (states). The states depend on the specific system in question. How is a piano An example of a quantized system? When you play a piano, you […]
Is gold a solute?
Is gold a solute? Not all solutions are liquids. Solutions can also be solids. In a solid solution, both the solvent and the solute are solids. In this case, gold is the solvent and the other metals are the solutes. Why is gold a homogeneous mixture? Because the material is uniform throughout, it is homogeneous. […]
Why does temperature increase as pressure increases?
Why does temperature increase as pressure increases? The temperature of the gas is proportional to the average kinetic energy of its molecules. Faster moving particles will collide with the container walls more frequently and with greater force. This causes the force on the walls of the container to increase and so the pressure increases. What […]
Which group is very unreactive?
Which group is very unreactive? noble gases Why does group 18 have no charge? Noble gases are relatively inert and nonreactive due to their full outer shell of electrons. Having a full valence shell of 8 electrons means that the atom is already in its most stable state, and thus, there is no need for […]
Which of the following best describes a ray?
Which of the following best describes a ray? Answer: any of a set of straight lines passing through one point. Which best describes Sawyer’s error? Which best describes Sawyer’s error? The wave fronts should be perpendicular to the direction in which the waves move. Which pair shows the law of reflection? The answer is A […]
What are the two primary purpose of note taking?
What are the two primary purpose of note taking? The primary purpose of note taking is to encourage active learning and to prepare study materials for exams. Developing note taking skills should help you organize information into an understandable format that will assist in your studying process. There are multiple methods for taking notes. What […]
What are 2 types of diffusion?
What are 2 types of diffusion? Diffusion can be classified into two main types: Simple diffusion and facilitated diffusion. Why does simple diffusion happen? The kinetic energy of the molecules results in random motion, causing diffusion. In simple diffusion, this process proceeds without the aid of a transport protein. it is the random motion of […]
What is the difference between radar and Doppler radar?
What is the difference between radar and Doppler radar? How is Doppler different from conventional radar? Conventional radar detects the presence of dense objects (such as precipitation) in the field, while the Doppler system detects a phase shift between the outgoing and incoming signals. What does a tornado look like on Doppler radar? Meteorologists look […]
Is pure water blue?
