problems in solid state physics

The cells discussed above use a liquid electrolyte, one cathode and an anode. Some of the major disadvantages of these cells are leakage on long term storage, corrosion due to the use of liquid acidic/alkaline solution, short life, low weightage per kg mass of the cell and limit on miniaturization...

Matter occurs in four states: Solid, Liquid, Gas and Plas..

States of Matter - Normally matter exists in three forms: Solid Liquid Gases Heat energy can bring about a change of state in matter from solid to liquid and liquid to gaseous state. Suppose a solid is heated continuously at constant press..

Steam is passed into the steam chamber and a stream of water is maintained. The temperatures of all the four thermometers rise initially and ultimately become constant when the steady state is reached. The readings q 1 , q 2 , q 3 , and q 4 are noted in steady state..

It is the process of changing a solid into its liquid state. The temperature at which a solid changes to the liquid state is known as melting point. When a solid is heated, the molecules gain more kinetic energy and start vibrating with a greater v..

A solid has certain characteristics: According to modern theory, the molecules of a solid are fixed in relation to each other. They vibrate in place, but do not wander around. This accounts for the fact that a solid keeps its own shape. Solids are usually cry..

Take a few pieces of ice in a beaker. Insert a thermometer. Note the temperature. You will observe it to be 0 0 C. Now place the beaker on a flame and heat it. Ice starts melting. As you supply heat to ice, its temperature should rise. But you will find that the temperature of ice remains at 0 0 C..

Heat and Motion (Kinetic Theory of Heat) - Under normal conditions matter exists in three forms: solid liquid gas Matter is made up of atoms and molecules. These atoms in molecules are in a state of continuous motion. For example, molecules and atoms of a solid can hav..
