Solar energy (energy released by the sun) has been around for as long as the sun has - an approximate of around 5 million years. In 1861, Angute Mouchout was the first person to convert solar power into energy, when he created a steam engine that ran entirely on solar power. Solar power is one of the only renewable sources on our planet, but is still very inefficient.

In general terms here is how the solar system came into being. An earlier incredibly massive star exploded into a supernova at the end of its life, leaving a huge cloud of gases and debris. Out of this cloud a section began to come together under the force of its own gravity. The gases that formed the sun gathered in the center, and an accretion disk of materials began swirling around it. The accretion disk is material that began falling toward the central mass but fell into a swirling or orbital pattern rather than falling to the center. This disk of gasses and other debris eventually formed the planets. Solar wind rushing out from the young sun pushed the lighter gases away from itself, and this is why the rocky planets are closer in and the gas giants are farther out.
The Sun was formed about 4.57 billion years ago when a hydrogen mhttp://wiki.answers.com/wiki/Molecular_cloud collapsed. When the hydrogen atoms got transformed into helium atoms, heat energy was released and all this resulted in the formation of a massive star; our Sun.

Why is emulsion paint described as a colloid?

In a colloid, particles of one substance are mixed and dispersed with particles of another substance - but they are not dissolved in it. In an paint the pigment is dispersed in the liquid formed from the binding medium and solvent solution. Hope this helps :)


How can the word ''colloid'' be used in a sentence?

Wallpaper paste is a colloid. When you mix flour in water you form a colloid.


From what did earth probably form?

The earth poabaly formed by dust particles, rocks, and ice in space after the "Big Bang" .


What concepts explains how the rainbow is formed?

A rainbow is formed when sunlight is refracted, reflected, and dispersed in water droplets in the sky, creating a spectrum of colors. The primary concept behind this is called dispersion, where different wavelengths of light are refracted at slightly different angles, revealing the various colors of the rainbow.


How is solution formed in chemistry?

A solution is formed when a solute (substance being dissolved) is evenly dispersed in a solvent (the dissolving medium) at a molecular level. This occurs when the attractive forces between the solute and solvent molecules are stronger than the forces holding the solute particles together. The result is a homogeneous mixture with solute particles distributed uniformly throughout the solvent.


What are the similarities of colloids and suspension?

Colloids and suspensions are both heterogeneous mixtures where particles are dispersed within a medium. However, colloids have smaller particles that do not settle out over time due to Brownian motion, while suspensions have larger particles that settle out due to gravity. Both colloids and suspensions can scatter light, making their solutions appear cloudy or opaque.


What are the three types of colloidal system?

The three types of colloidal systems are sol, gel, and emulsion. In a sol, solid particles are dispersed in a liquid; in a gel, a network of solid particles is formed within a liquid; and in an emulsion, two immiscible liquids are dispersed in each other with the help of an emulsifying agent.


Examples of suspension in science?

A colloid is a type of suspension where particles are dispersed in a medium (such as milk or fog). Sedimentary rocks are formed by the settling and accumulation of suspended particles in water or air. Suspended load in rivers refers to the particles carried by the flowing water, which can include sand, silt, and clay.


Is dissolution of sulfur in carbon disulphide is chemical or physical change?

The dissolution of sulfur in carbon disulfide is a physical change because no new substances are formed. The sulfur particles are still sulfur particles, they are just dispersed within the carbon disulfide, similar to dissolving sugar in water.


What are colloids made of?

There are two ways that colloids are formed. One is through reduction of larger particles to colloidal size. Another is condensation of smaller particles.


What is a special mixture formed when a material dissolves in water?

A special mixture formed when a material dissolves in water is called a solution. In a solution, the material that dissolves is known as the solute, while water is the solvent. The solute particles are dispersed and evenly distributed throughout the solvent, resulting in a homogeneous mixture.


Which does not let light pass through solutionmixturecolloidor suspension?

colloid is one of the three primary types of mixtures, with the other two being a solution and suspension. A colloid is a solution that has particles ranging between 1 and 1000 nanometers in diameter, yet are still able to remain evenly distributed throughout the solution. These are also known as colloidal dispersions because the substances remain dispersed and do not settle to the bottom of the container. In colloids, one substance is evenly dispersed in another. The substance being dispersed is referred to as being in the dispersed phase, while the substance in which it is dispersed is in the continuous phase.Properties of ColloidsIn order to be classified as a colloid, the substance in the dispersed phase must be larger than the size of a molecule but smaller than what can be seen with the naked eye. This can be more precisely quantified as one or more of the substance's dimensions must be between 1 and 1000 nanometers. If the dimensions are smaller than this the substance is considered a solution and if they are larger than the substance is a suspension. A common method of classifying colloids is based on the phase of the dispersed substance and what phase it is dispersed in. The types of colloids includes sol, emulsion, foam, and aerosol.Sol is a colloidal suspension with solid particles in a liquid.Emulsion is between two liquids.Foam is formed when many gas particles are trapped in a liquid or solid.Aerosol contains small particles of liquid or solid dispersed in a gas.When the dispersion medium is water, the colloidal system is often referred to as a hydrocolloid. The particles in the dispersed phase can take place in different phases depending on how much water is available. For example, Jello powder mixed in with water creates a hydrocolloid. A common use for hydrocolloids is in the creation of medical dressings.
