What happens during fluorescence to the energy which gets absorbed but not emitted as fluorescence by the atom?
If energy is absorbed but not emitted as fluorescence it may:
- increase the energy of the molecules - manifest as an increase in temperature
- use the energy to power a chemical reaction - manifest as a change in composition
- release the energy at a wavelength other than that being observed for fluorescence.

What is the energy added during a phase change?
They move around faster or slower depending on the type of change.
Which particle is emitted during the nuclear decay of Ne-19?
During the nuclear decay of Ne-19, a positron is emitted.
What happens to energy during a chemical reaction?
During a chemical reaction, energy is either absorbed or released. If energy is released, it is usually in the form of heat. If energy is absorbed, the reaction requires an external energy source to proceed.
What happens to the energy absorbed during and endothermic reaction?
During an endothermic reaction, energy is absorbed from the surroundings, typically in the form of heat. This energy is used to break chemical bonds in the reactants, allowing the reaction to proceed. As a result, the temperature of the surrounding environment may decrease, and the products of the reaction have higher energy than the reactants. Overall, the absorbed energy is stored within the chemical bonds of the products.
What type of radiation does earth's surface radiate to cool down?
The Earth's surface radiates thermal infrared radiation to cool down. This energy is absorbed from the sun during the day and then emitted as heat at night to balance the energy received.
What is the emission of colored light rays during exposure to ulraviolet light?
Fluorescence. It happens when atoms' electrons absorb light at one frequency and emit at other (usually lower) frequencies. Sometimes two photons are absorbed by the same electron, and emitted as a single higher frequency, but this is not common.
What is a photometric titration?
A photometric titration is a method of analyzing a solution by measuring the intensity of light absorbed or emitted by the solution during a titration process. This technique is commonly used to determine the concentration of an analyte in a sample based on the amount of light absorbed or emitted at specific wavelengths.
The emission of colored light rays by a substance during exposure to ultraviolet light?
This phenomenon is called fluorescence. When a substance absorbs ultraviolet light, it becomes excited and emits visible light of different colors. The emitted light is characteristic of the substance and can be used in various applications such as fluorescent microscopy, forensics, and material analysis.
What is the energy added during a phase change?
They move around faster or slower depending on the type of change.
What happens to the unfertilized eggs in the human female?
They are absorbed and later passed out during menstruation.
What happens to the solar energy absorbed by plants during photosyntesis?
Stored as chemical energy in glucose
What happens to the carbon that does not end up as carbon dioxide during cellular respiration?
it is absorbed back into the matrix
What does a negative net radiation value mean?
It simple that outgoing or emitted radiation is more. this usually happens during night times.
What can scientists measure to provide evidence that electrons can move from one energy level to another?
Scientists can measure the amount of energy absorbed or emitted by electrons as they transition between energy levels. This can be done through spectroscopy techniques like absorption or emission spectroscopy, which can reveal the specific wavelengths of light absorbed or emitted during these transitions. By analyzing these spectral lines, scientists can provide evidence that electrons can indeed move between energy levels.
What is the recommended mounting medium for fluorescence microscopy?
The recommended mounting medium for fluorescence microscopy is an anti-fade mounting medium, such as Vectashield or ProLong Gold, which helps preserve the fluorescence signal and prevent fading during imaging.
