Heat of Mixing: Ethanol and Water Abstract The temperature change when known amounts of water and ethanol were mixed was determined to see the enthalpy change in an isothermal and isobaric environment. Agreeable data was found compared to similar experiments. As the mole fraction increased of the solution so did the enthalpy until a certain limit of about 0.32. Since water’s structure and unique properties affect many aspects of a solution‚ the solutions enthalpy’s decreased at a certain time

I will now look how I perceive colour on the percept. When analysing sensory perception I explained the process of how the eyes see the percept through wavelengths of light‚ which is transmitted at different wavelengths and frequencies. The main source of light would be sunlight. The scale of the wavelength and frequency for light determines the colour seen‚ as every colour has its own wavelength and frequency. When perceiving colour the spectrum of the wavelengths stretches from short wavelengths
