or or Now, if V 1 is the volume of a gas at temperature T 1 and pressure P 1 . V 2 is the volume of same amount of gas at temperature T 2 and pressure P 2 , th..

Helium - Neon Gas Laser - The figure shows the elements of a type of laser that is often found in student laboratories. The glass discharge tube is filled with a 80%-20% mixture of the inert gases helium and neon. Helium is the "pumping" medium and neon is the "lasing" medium. The above f..

Since n is greater than one, qualitatively, it can be said that the extent of adsorption x/m does not increase rapidly with increase in pressure as shown in the above figure. Freundlich equation can be transformed into a linear form by taking the logarithms on both sides of the equation ..

Wave trains for laser light may be several hundred kilometers long. Interference fringes can be set up by combining two beams that have followed separate paths whose lengths differ by as much as this amount. The corresponding coherence length for light from a tungsten filament lamp or a ..

The apparatus is set up as shown in figure 6.15. The combustion tube is heated strongly and concentrated nitric acid is allowed to flow into it. Due to the heat, it decomposes, liberating the corresponding gases. Reddish yellow fumes of nitrogen dioxide, water vapour and a colourless..

When coal is heated without air, it does not burn but produces many by-products. This process of heating coal in the absence of air is called destructive distillation of coal. The main by products are: coke coal tar amino acid liquor coal gas The destructive distillation of coal can be ca..

Different forms of numbers Scientific notation, square roots, exponents, radicals, absolute value, factorial, logarithms Properties of numbers Estimation of solutions Sequences and series Proportionality/direct variation, exponential/fractional expressions Patterns, relations and ..

2 gas on the metal and H + of the solution, an equilibrium is established. This constitutes Hydrogen electrode represented as pt, H 2 /H + . Since the oxide ion in solution forms OH - instead of remaining as O - 2 . The Electrical potential difference set up between the..

Fill a test tube with mercury and invent it over a petridish containing mercury. Introduce some germinating seeds into the test tube. The seeds will immediately rise to top. Leave the set up for about a day. It is noted that the mercury level in the tube falls and the space above the merc..

The apparatus is set up as shown in figure 10.4. Powdered coal is taken in the test tube A. Test tube B contains a small amount of water. When test tube A is strongly heated, black dust like particles get collected near the mouth of the test tube. This is called gas carbon...
