From the above ideal gas equation: ..

The specific heat of a substance is the amount of heat required to increase the temperature of a unit mass of it through a unit temperature. Its units in cgs system are cal g -1 o C -1 . In mks system, it is measured in kilocal kg - 1 o C - 1 . The SI unit is J kg - 1 K - 1 . The above de..

Another simple equation of state is the one for an ideal gas. The figure below shows an experimental setup to study the behavior of a gas. The cylinder has a movable piston to vary the volume, heating can vary the temperature, and we can pump the desired amount of any gas..

Liquid-Gas (vapour) Equilibrium - When a liquid is placed in an open container it disappears completely after some time. However, when the same liquid is placed in a closed container, even after a long period only a part of the liquid disappears. The obvious difference is that the vapours..

v are measured in J K - 1 mol - 1 . C p is greater than C v . If a gas is heated at constant volume, the gas does no work against external pressure. In this case, the whole of the heat energy supplied to the gas is spent in raising the temperature o..

The volume of a substance is the space occupied by it. A gas occupies the entire volume of the container available to it. The measurement of the volume of a gas only requires the measurement of the volume of the container enclosing i..

: Addition of iodine to salt to prevent goitre). Prevention of breeding of harmful insects. Control of pollution through the Central and State Pollution Control Boards. Administration of vaccinations against communicable diseases like tuberculosis, diphtheria, whooping cough, tetanus, measles, hepa..

It is clear from equation (2) that the mean kinetic energy of a molecule is directly proportional to the Kelvin (or absolute) temperature of a gas. When the temperature of the gas is increased, the mean kinetic energy of the molecules increases. On the other hand, when heat ..

It is not possible to measure directly the potential developed at interface of the metal gas and its ions in solution using voltmeter. Hence the electrode whose single electrode potential has to be determined is coupled with another electrode of known potential and the emf..

Community health refers to health issues concerning a common group of people. It is different from individual health issues in the sense that symptoms, control measures are community oriented. Large part of community health deals with preventive medicines as well as preventive care. Preve..
