Rust is a chemical phenomenon that we find in materials made of iron or other metals as a result of oxidation and reduction reactions. For example, strontium produces a deep red color, sodium produces a yellow color, copper produces a green color, and potassium produces a lilac color. Fireworksįireworks are chemical phenomena that are produced by the heating of metals in an explosion. Here are some examples of chemical phenomena. In everyday life we come across different chemical phenomena that sometimes go unnoticed. What is Chemical PhenomenaĬhemical phenomena are the events that occur when the composition of matter is altered. When lightning strikes, so much energy is released that it lights up the sky and generates heat. This is due to a separation of electrical charges between the earth’s surface and the clouds. They are electrical discharges that generally occur during storms. Lightning or lightning bolts are electromagnetic phenomena that occur in the atmosphere. They are widely used for the transmission of data, images and sound. This happens because the light is reflected internally by the cable, causing it to bounce throughout the fiber without getting lost in the external environment. Optical fibers are a physical optical phenomenon characterized by the fact that light travels through long glass or plastic cables or fibers. It is an optical illusion that makes us perceive the presence of water in the distance, which is not real. MiragesĪ mirage is an optical physical phenomenon that occurs because light bends as it passes through layers of air with different temperatures. The water droplets in this case act like a prism, separating the bands of colors that make up the light. The rainbow is a luminous physical phenomenon that we can observe in the sky when sunlight is reflected and refracted by raindrops. This is known as “breaking the sound barrier.” Rainbow When an airplane exceeds this speed, a noise similar to an explosion is produced. Sound is a wave that travels through the air at a speed of 343 meters per second. The sound barrier is a physical acoustic phenomenon resulting from the collision of sound waves in the air. Here are some examples of physical phenomena. These phenomena can be explained by the laws of physics. Physical phenomena are events that occur in nature in which the composition of matter is not altered. Difference between Physical and Chemical Phenomena What is Physical Phenomena Let’s check below what is the difference between physical and chemical phenomena. Physics and chemistry are the sciences that allow us to explain all these phenomena. We get physical and chemical phenomena in our day to day, from boiling water, frying an egg to the blue color of the sky. The chemical phenomena are events that occur due to changes in the composition of matter. The physical phenomena are those events or events where the composition is not modified material, ie, maintains its physical properties.
