5. Wien’s law explains that objects of different temperatures emit spectra that peak at different wavelengths. Hotter objects emit shorter wavelengths, thus appearing bluer, whilst colder objects emit longer wavelengths, appearing redder. A star’s surface temperature can be deciphered using this method by seeing its …
Introduction The utilization of any complex molecule for energy by an organism is dependent on a process called hydrolysis. Hydrolysis breaks complex molecules into simpler molecules using water. Similarly, the process that is the reverse of this is called dehydration synthesis, which removes water from …
