White light is spread out into its spectral components by a diffraction grating. If the grating has 2,030 grooves per centimeter, at what angle (in degrees) does red light of wavelength 640 nm appear in first order

the answer is false. this is because for ice to melt, it requires latent heat of melting. latent heat means heat energy required to change phase without any increase in temperatures. therefore, the ice will take energy from the environment to melt hence atmospheric temperatures will reduce.
