When different atoms join together, they are called a compound. Compounds are made of molecules (so molecules could be an alternate answer, but not all molecules are compounds)
Answer:
Given
mass of solute (m) =20.5g
mass of solvent( ms) =155g
solution
malality =mX1000/mrxms
M=20.5x1000/62x155
M=2.1332
- The wavelength range of Infrared radiation is 700 nanometers to 1 millimeter.
- The sun emits mainly near-infrared which is mainly composed of wavelength below 4 micrometers.
- The thermal range of infrared ranges between wavelengths 3.5 and 2.0 micrometers
Explanation:
The wavelength range of Infrared radiation is 700 nanometers to 1 millimeter. This also translates to a frequency range of 430 TeraHertz to 300 Giga Hertz.
Because the sun is a star and is hot in comparison to earth and other planetary bodies, the bigger range of infrared radiation it emits is in the near-infrared which is mainly composed of wavelength below 4 micrometers.
The earth's surface produces infrared radiation of the mid-infrared range while cooler substances will produce far-infrared range
The thermal range of infrared ranges between wavelengths 3.5 and 2.0 micrometers and is produced by black bodies.
