Is heating curve exothermic?
Is heating curve exothermic? On any heating curve, energy is added and therefore it is always endothermic. On any cooling curve, energy is released and therefore it is always exothermic. Why is freezing exothermic? When water becomes a solid, it releases heat, warming up its surroundings. This makes freezing an exothermic reaction. Usually, this heat […]

Where are feature detectors? Perception is created in part through the simultaneous action of thousands of feature detector neurons—specialized neurons, located in the visual cortex, that respond to the strength, angles, shapes, edges, and movements of a visual stimulus (Kelsey, 1997; Livingstone & Hubel, 1988).

How many dimensions are quantum dot excitons confined?
How many dimensions are quantum dot excitons confined? three Are all quantum dots toxic? Cadmium-containing QDs can kill cells in culture. Many researchers then assume that because QDs are toxic to cells, they must be toxic to humans. In addition, many researchers classify QDs as a homogeneous group of materials. Therefore, if CdSe QDs are […]
Can we make energy from mass?
Can we make energy from mass? Specifically, small amounts of mass are turned into energy from the breaking up (fission) or combination (fusion) of the nuclei of atoms. Even spontaneous radioactive decay converts a bit of mass into incredible amounts of energy. Can you create mass from light? Breit and Wheeler suggested that it should […]
