Quantization of energy lab Hypothesis: Make a prediction that describes the relationship between the composition of an unknown substance and its emission spectrum. For example, “If each element can be identified by its , then the of an unknown star can be determined." variables: independent - dependent- control-

If each element can be identified by its spectrum then the composition of an unknown star can be determined

Explanation:

The chemical nature of the elements is that they absorb specific wavelength of light depending on their atom. By spectral analysis of the spectrum of emitted light by a body, the body's composition can therefore be determined. As such in order to determine the composition of distant bodies such as planets, stars and other celestial bodies scientists usually make use of spectroscopy.

? you expect us to answer this? ? this is your schoolwork, i don't think we can with this, i think it would considering being

conduction is the transfer of thermal energy (heat in transfer) due to collisions between the molecules in the object. collisions between adjacent atoms and molecules transfer kinetic energy from the warmer to the cooler object. the objects must be in physical contact.
