the peak intensity of radiation for a particular star occurs at a wavelength of 2.0 nanometers and what spectral band is this
Dmitry_Shevchenko [17]
For a given peak intensity of radiation of a star that occurs at a wavelength of 2 nanometers, this is located at the spectral band of an X-ray. An X-ray's wavelength typically goes from 0.1 nano meters to 10 nano meters. Given that, the wavelength of the star fits perfectly into the range of an X-ray

if the solvent-solute interactions are weaker than the average of the solvent-solvent and solute-solute interactions, then heat
Alex777 [14]

If the solvent-solute interactions are weaker than the average of the solvent-solvent and solute-solute interactions, then heat is absorbed from the surroundings and the overall mixing process is said to be endothermic process.

The endothermic process can be defined as the process in which the reactants the will absorbed the heat from the surroundings . the heat is gained from the surrounding in the endothermic process and the surroundings temperature will decreases.

The solvent - solute interaction < solute - solvent interaction \and the solute solute interaction then the solution may be or may not be formed.

Thus, then heat is absorbed from the surroundings and the overall mixing process is called as endothermic process.
