MATTER IN OUR SURROUNDINGS Since early times‚ human beings have been trying to understand their surroundings. Early Indian philosophers classified matter in the form of five basic elements – the “Panch Tatva”– air‚ earth‚ fire‚ sky and water. For a long time‚ two schools of thought prevailed regarding the nature of matter. One school believed matter to be continuous like a block of wood‚ whereas‚ the other thought that matter was made up of particles like sand. Activity ______________ 1.2 •

will help ensure man ’s survival. Solar Energy Solar energy is the generation of electricity from the sun. It is split up into two types‚ thermal and electric energy. These two subgroups mean that they heat up homes and generate electricity respectively. Solar energy‚ radiant light and heat from the sun‚ has been harnessed by humans since ancient times using a range of ever-evolving technologies. Solar energy technologies include solar heating‚ solar photovoltaics‚ solar thermal electricity‚ solar

fission or nuclear fusion reactions. The term refers to both the uncontrolled release of nuclear energy‚ as in atomic weapons‚ and to the controlled release of energy‚ as in nuclear power plants. A. Nuclear fission i. Nuclear fission‚ occurs when an atom splits in two‚ releasing a massive amount of energy and several subatomic particles called neutrons. These neutrons hit and split other atoms‚ beginning and sustaining the chain reaction. B. Nuclear fusion i. Nuclear fusion is a process in which

Nuclear fusion is when two atomic nuclei combine into one heavier nucleus. Nuclear fusion plays the role of providing energy for the Sun. This energy is created as nuclear fusion occurs following the steps of the proton-proton chain reaction. 3. How are sunspots and solar flares similar? How are they different

The energy that comes from nuclear fusion hinders the star from continuing to fail. When the star reaches this union‚ at the moment that the nuclear fusion comes to light what was gas is now a star. In this situation‚ the Sun is the after math. In the existence of the Sun it is where we are in the here and now. Through nuclear fusion the Sun keeps on burning.

Fusion Zone increases as the welding current increases because of more generation of heat at the interfaces of the two sheets. It is quite evident after the static tensile-shear test that
