example of a experiment

In its simplest form, it consists of a cylindrical glass tube about 50 cms long, closed at both ends called the discharge tube (or Crookes tube). The tube is fitted with two metallic electrodes, which are connected to a source of high voltage. It is filled with gas and the discharge tube is connec..

. We can now summarize the properties of mixtures as follows: A mixture may be homogenous or heterogeneous. The constituents of a mixture can be separated by physical means like filtration, evaporation, sublimation and magnetic separation. In the preparation of a mixture, energy is neither evolved ..

Take a pot with a young plant and rest it on its side so that the stem lies horizontally. Observe after a few days. Geotropism in Roots If a plant is rotated on a special apparatus called clinostat, it neutralizes the effect of gravity and the shoot continues to grow horizontally without any curvat..

Take hydrated copper (II) sulphate crystals in a test-tube and heat. On heating, the blue crystals in the test tube start turning white. Water vapours are released that condense on the cooler part of the test tube. Collect the water drops in a dish. The crystalline copper sulphate turns to amorpho..

Victor Meyer's method is used for the determination of molecular masses of volatile substance..

Two random experiments are said to be independent if for every pair of events E and F, where E is associated with the first experiment and F is associated with the second experiment, the probability of simultaneous occurrence of E and F, when the two experimentsh..
