Why Do Darker Colors Absorb More Heat Than Lighter Colors?
Why do darker colors absorb more heat than lighter Colors?

Have you ever wondered why on a hot summer day you would be wearing a black or dark blue t-shirt and in like 5 min you’ll already be sweating and it would be really hot while your friends that are wearing white or yellow t-shirts are all ok and don't seem affected by the heat. Have you ever thought what might cause this to happen? Well the color of our clothes is determined by a chemical dye that is added to the cloth at the factory when it’s being made. Now the energy of sunlight affects the atoms of the dye in 2 different ways. Now we know how electrons react when light is shining on the atoms. These electrons absorb a specific frequency of light and become “excited”, and emit a specific frequency of light, which we see as a color. And this frequency is directly related to the color in the clothes. When you look perfectly at white clothes, all the colors are being absorbed by the electron in the atoms of the elements in the dye, causing the electrons to become “excited”, and emit all frequencies of light back to your eyes. All the energy of the photons red, orange, yellow, blue, indigo, and violet light is sent right back to the air around the white shirt. So none of the energy is absorbed by atoms and converted into kinetic energy of atoms. Temperature measures the kinetic energy of the atoms. So if there is no increase of kinetic energy this means that there will be no increase of temperature in the lighter colored clothes. Now when you look at black clothes, none of the colors are being absorbed by the electron in the atoms of the elements in the dye, so ALL of the energy of the photons of red, orange, yellow, blue, indigo, and violet light is absorbed by the atoms of the elements of which the shirt is composed. So all of the energy is converted into kinetic energy of atoms. Temperature measures the kinetic energy of the atoms. High increase in kinetic energy means high increase of

    Light is usually viewed as a result of the heating of a substance. The higher the temperature at which the substance is heated, the greater the vibrations that lead to certain light intensity given off by the molecule. It is this same theory that suggests why steel glows red hot when heated to high enough temperatures. The process of light emissions can also be induces through other means. 1…

    When atoms or ions in ground state are heated to a higher temperature, some electrons absorb enough energy to move them to higher energy levels. This is known as the excited state. However, the excited configuration is unstable, and the electrons must return back to their positions in the lower energy level. As they return, the energy that was previously absorbed is now emitted in the form of electromagnetic energy. This energy can be displayed in the form of visible light. The main purpose/objective of this lab was to observe the characteristic colors produced by certain metallic ions when they are vaporized in a flame. Another main objective of this lab was identifying the unknown metallic ions by means of flame tests. In this lab, this is what was supposed to be…

    When atoms absorb energy, electrons move into higher energy levels, and these electrons lose energy by emitting light when they return to lower energy levels. Energy levels are fixed energies that electrons can have. Ordinary light is made up of a mixture of all the wavelengths of light. Light, consisting of waves consists of wavelength and frequencies that are inversely proportional to each other, so as the wavelength of light increases,…

    As the substance heats up, the electrons gain energy from the flame to move to a higher level of energy. At this higher energy level, the electrons become unstable and start to come back down to the “ground state” (lower energy levels). As this happens, the electrons in the substance release a certain amount of energy, which we see as a color…

    When white light passes through a prism its component wavelengths are bent at different angles. This produces a rainbow of colors known as a continuous spectrum. If, however, the light emitted from hot gases or energized ions is viewed in a similar manner, isolated bands of color are observed. Each band represents a specific energy level change of electrons in the atoms. Since the atoms of each element contain unique…

    In every reaction, energy is transferred between a system and its environment. A system encompasses the substances that are involved in a reaction, and everything else in the universe other than the system is called the environment. The standard SI unit of energy is Joules (J). Temperature is the level of excitement of the atoms in a substance. In most cases, energy is transferred by heat. Heat is the energy released from a change in temperature. The standard units for heat and temperature are in degrees Celsius or Kelvin (both have the same increment between each degree, the difference is that Celsius is based off…

    In this experiment we are trying to observe this amazing phenomenon. Heating up different elements using a flame, we are able to see the change in states and the emitted photons. In the process we will try to answer questions such as: how does the amount of energy absorbed by electrons affect the color of light produced? What does the light produced tell us about the energy of the emitted photon? What has more energy, a photon that takes one big step, or photons that take many steps? Our objective is to observe the unique color of light emitted by each element, and determine the…

    Energy is important to my topic because we are testing the effects of light energy on a plants development. Energy is the ability to do work. Some types of energy are light, thermal, sound, nuclear, electric, chemical, and mechanical energy. Energy is transferred from one place to another with waves. All waves have amplitude, wavelength, and frequency. The electromagnetic spectrum is the range of wavelengths or frequencies over which electromagnetic radiation extends. In the electromagnetic spectrum the visible light falls in the middle. Visible light waves are the only electromagnetic waves we can see. We see the waves as all the colors of the rainbow. Each color has a different wavelength. Red has the longest wavelength and violet has the shortest wavelength. When all the waves are seen together, they make white light. The difference between the colors we see is wave length.…
