Why Marie Curie is a hero? She was a scientist that discovered two elements, polonium and radium, she also invented techniques for isolating radioactive isotopes. She also discovered radiation that could kill human cells. During World War 1 she was sent to work with French builders and she helped design the x-ray. What is a […]
How does temperature affect ideal gas law?
How does temperature affect ideal gas law? As the temperature increases, the average kinetic energy increases as does the velocity of the gas particles hitting the walls of the container. The force exerted by the particles per unit of area on the container is the pressure, so as the temperature increases the pressure must also […]
When something is painted red What color is most absorbed?
When something is painted red What color is most absorbed? red light, is absorbed. What color of light are our eyes most sensitive? green light Why are red green and blue called additive primary colors quizlet? Why are red, green, and blue called the additive primary colors? Adding appropriate amounts of red plus green plus […]
What is the electrostatic attraction?
What is the electrostatic attraction? Electrostatic attraction refers to the electrostatic force of long-range interaction occurring between the attractive electrostatic adsorption in aqueous solution with differently charged particles or uncharged particles. What increases electrostatic attraction? The net attractive electrostatic attraction is increased as the nuclear charge increases. Electrons are being added to successive energy levels […]
What occurs when an atom loses an electron?
What happens when you wrap a wire around a nail?
What happens when you wrap a wire around a nail? By simply wrapping wire that has an electrical current running through it around a nail, you can make an electromagnet. When the electric current moves through a wire, it makes a magnetic field. If you coil the wire around and around, it will make the […]
What is experiment in data collection?
What is experiment in data collection? Experiment. An experiment is a controlled study in which the researcher attempts to understand cause-and-effect relationships. The study is “controlled” in the sense that the researcher controls (1) how subjects are assigned to groups and (2) which treatments each group receives. What is the purpose of data in an […]
What are the 3 classifications of carbohydrates?
What are the 3 classifications of carbohydrates? Carbohydrates are classified into three subtypes: monosaccharides, disaccharides, and polysaccharides. What are the classifications of carbohydrates? Carbohydrates are divided into four types: monosaccharides, disaccharides, oligosaccharides, and polysaccharides. Monosaccharides consist of a simple sugar; that is, they have the chemical formula C6H12O6. Disaccharides are two simple sugars. Which is […]
What happens if you increase the frequency?
What happens if you increase the frequency? The number of complete wavelengths in a given unit of time is called frequency (f). As a wavelength increases in size, its frequency and energy (E) decrease. From these equations you may realize that as the frequency increases, the wavelength gets shorter. As the frequency decreases, the wavelength […]
Does burning reduce mass?
Does burning reduce mass? Burning and other changes in matter do not destroy matter. The mass of matter is always the same before and after the changes occur. The law of conservation of mass states that matter cannot be created or destroyed. Why does burning steel wool increase the mass? The heat and large amount […]
