ScienceForDummies - Week 7

 Week 7: What is Fire?

After a week of polling, the winning topic is "What is Fire?" under the Physics section. 

Everybody knows fire, but if they are asked "What is it?", we usually associate it with heat. Fire is actually a process of oxidation (the gain of oxygen), that is rapid and releases energy to its surroundings in the form of heat and light. The flame of the fire is a visible part of the fire consistinf of carbon dioxide, water vapor, oxygen and nitrogen. 

Fire produces plasma when hot enough, and they can have different colors accoording to the substances of the fire. Fire can cause the burning process, or combustion, where oxygen and fuel (the material of fires causing the heat and energy involved)  react and create smoke and energy. This is also how fires begin - the reaction of combustion.

Combustion is also responsible in important technologies such as heating, motors/cars, energy, and fireworks.

ScienceForDummies: Electricity

 Hello! Today's episode is about electricity. Electricity relies on the idea of electrons. Electrons is a subatomic particle - a particle which makes up of an ato . It has a negative charge and there are sixteen of them in a single atom. So how do they relate to electricity? Electricity is a physical phenomena where something moves that has an "electric charge". This idea of electricity is related to magnetism, because it is related to movement. Simply, it is a type og energy that consists of the movement of electrons. Electricity generates an electric current, and things can conduct electricity to make it move faster and insulate it to make it slower.

ScienceForDummies: Heat and Light

 Hello!  Heat - Heat is an energy that is transferred from one body to another because of a difference in temperature. Heat flows from hot bodies to cold bodies ("bodies" meaning objects or matter). Hear energy is created when aroms move faster and collidep. It is also known as thermal energy, and heat is the transfer of said energy. Light - Light is a kind of radiation that can be perceived by the human eye. It has wavelengths which can differ, forming what we know as colors. It can travel, refract, reflect, diffract, interfere, and disperse, etc. These things is possible by light.

ScienceForDummies: Matter and Energy

 Hello! Today is about matter and energy, and the second week of the Physics series. What is Matter? Matter is a physical substance which occupies space and has mass, distinct from energy. Matter is physical, so it does not have a rational nor conscious nature, at least itself. The popular understanding is that there are three states of matter, which is true, though there are other things considered as states of matters, the most popular of which being plasma. Basically, matter is a physical object. But it says "distinct from energy". What is energy, then? What is Energy? Simply, energy is a capacity to do something, especially moving something else. Energy falls into two central categories: kinetic energy and potential energy. What is the difference between the two types? Kinetic energy is in movement, while potential energy is not used, but usable to work.
