What happens to the electrons after absorbing energy from light?
After absorbing energy from light, electrons in an atom can move to higher energy levels or be released from the atom altogether in a process called photoemission.
What are the properties and applications of light-absorbing materials?
Light-absorbing materials have the property of absorbing light energy across a range of wavelengths. These materials are used in various applications such as solar panels, photodetectors, and camouflage technology. They are important for converting light energy into other forms of energy or for controlling the visibility of objects.
What happens to the light waves during absorption?
During absorption, light waves transfer their energy to the absorbing material, causing the electrons in the material to move to higher energy levels. This leads to an increase in the internal energy of the absorbing material.
What term is defined as a measure of the average kinetic energy of the particles in a sample of matter?
Temperature is defined as a measure of the average kinetic energy of the particles in a sample of matter. It indicates how hot or cold an object is.
What does absorb heat mean?
Absorbing heat means taking in thermal energy from the surroundings, causing a temperature increase in the absorbing material. This process is common in objects or substances that have the ability to absorb and store heat energy.
What term refers to a chemical reaction that absorbs heat energy?
Absorbing energy from the surroundings is endothermic. (The opposite - releasing energy to the surroundings - is exothermic).
Where does the energy term appear in the equation for an exothermic reaction?
In an exothermic reaction, the energy term appears as a product in the chemical equation. This indicates that energy is released as the reaction proceeds, resulting in a net decrease of energy in the surroundings.
Is chocolate melting absorbing or releasing energy?
Melting chocolate requires energy input because the solid chocolate is transitioning into a liquid state. The energy input breaks the molecular bonds holding the solid together, absorbing energy in the process.
What is the difference between energy releasing reaction and energy absorbing action?
Beacuse when you release energy out of your body or somthing, somthing has to take in the energy so absorbing;SO, it's like a chain reaction you release somthing els takes in, like humans breath oxygen plants breath our carbon dioxide and plants give us oxygenSo, it differs because when energy-realses somthing needs to take that energy in as in absorbing
What happens to the electrons after absorbing energy from light?

Plants take in energy by absorbing what?
sunlight!
Why do energy absorbing reactions react spontaneous?
it doesn't its energy releasing reaction
What challenges of life are in soil?
absorbing energy reproduce
What happens to the energy of light absorbed ina an absorbing filter?
It changes to heat energy.
What is a reaction which takes in energy?
endothermic
What is the significance of a negative enthalpy change in a chemical reaction?
A negative enthalpy change in a chemical reaction indicates that the reaction is exothermic, meaning it releases heat energy to the surroundings. This is significant because it shows that the reaction is giving off energy rather than absorbing it, which can affect the temperature and overall energy balance of the system.
