Is more energy absorbed than released is the result of an endothermic chemical reaction?
In an endothermic reaction, heat is taken in from the environment. Heat is a form of energy. Therefore, energy is taken in, i.e. absorbed.
When an atom loses one or more electrons to form a positive ion the energy is?
When an atom loses one or more electrons to form a positive ion, the energy required is known as ionization energy. This is the energy needed to remove an electron from the atom.
Is absorption an intensive or extensive property?
Absorption is an extensive property because it depends on the amount of substance being absorbed. The more of a substance is present, the greater the absorption.
Does water temp affect its absorption rate?
Yes, water temperature does affect its absorption rate. Generally, warmer water can enhance the solubility of certain substances, allowing them to be absorbed more quickly compared to colder water. Additionally, higher temperatures can increase the kinetic energy of molecules, facilitating faster movement and absorption. However, the specific impact can vary depending on the substance being dissolved or absorbed.
Energy is absorbed when a nucleus is split during a nuclear reaction?
Yes, during a nuclear fission reaction, a nucleus splits into two or more smaller nuclei, releasing a large amount of energy in the process. This energy is released due to the conversion of mass into energy as per Einstein's famous equation, E=mc^2.
What is a reaction called in which heat energy is absorbed?
An endothermic reaction is one in which heat energy is absorbed from the surroundings. In these reactions, the products have more energy than the reactants. Examples include photosynthesis and the melting of ice.
When energy released or absorbed?
Energy is released when a chemical reaction is exothermic, meaning that the products have less energy than the reactants. Energy is absorbed in an endothermic reaction, where the products have more energy than the reactants.
When iodine goes from iodine to iodine gas in energy absorbed or released?
Energy is absorbed because the iodine is going from a liquid to a gas. This means that the iodine molecules are moving faster so they had to have absorbed more energy to do this.
What is the relationship between frequency and sound absorption?
Frequency and sound absorption are closely related as different materials have varying absorption properties at different frequencies. Generally, high frequencies are absorbed more easily than low frequencies due to the smaller wavelength and higher energy associated with high frequency sound waves. Different materials have specific absorption coefficients that dictate how much sound energy is absorbed at different frequencies.
Is more energy absorbed than released is the result of an endothermic chemical reaction?
In an endothermic reaction, heat is taken in from the environment. Heat is a form of energy. Therefore, energy is taken in, i.e. absorbed.
Is photoelectric absorption high kvp?
No, photoelectric absorption decreases with increasing photon energy (kVp). This is because higher-energy photons are more likely to be transmitted through the material or undergo Compton scattering rather than being absorbed through the photoelectric effect.
Do endergonic reactions absorb more energy than they release?
Yes, endergonic reactions absorb more energy than they release. These reactions require an input of energy in order to proceed, and the energy absorbed is greater than the energy released during the reaction.
When an atom loses one or more electrons to form a positive ion the energy is?
When an atom loses one or more electrons to form a positive ion, the energy required is known as ionization energy. This is the energy needed to remove an electron from the atom.

Additionally, higher temperatures can increase the kinetic energy of molecules, facilitating faster movement and absorption. However, the specific impact can vary depending on the substance being dissolved or absorbed.
How is thermal energy involed in chemical reactions?
Thermal energy is involved in chemical reactions by providing the necessary activation energy for the reaction to occur. Increasing the temperature increases the kinetic energy of the molecules, making them more likely to collide with enough energy to react. Additionally, some reactions are exothermic, releasing thermal energy as a byproduct.
What is the simple definition of optical density and how does it relate to the absorption of light?
Optical density is a measure of how much light is absorbed by a substance. It is related to the absorption of light because the higher the optical density, the more light is absorbed by the substance.
