The rms speed of an oxygen molecule in a sample at 300 K is about 480m/s. This does not mean that the speed of each molecule is 480 m/s. Many of the molecules have speed less than 480m/s and many have speed more than 480m/s. Maxwell derived an equation giving the distribution of mol..

The volume of a given mass of a dry gas is inversely proportional to its pressure, temperature remaining constant. Robert Boyle (1627 - 1691) discovered this law in 1662 and it was named after him. It can be restated as "The product of the volume and pressure of a given mass of dry gas is..

This law was proposed by Louis Proust in 1799, which states that: 'A chemical compound always consists of the same elements combined together in the same ratio, irrespective of the method of preparation or the source from where it is taken'. For example, water is always found to contain ..

The direction of magnetic field around a current carrying conductor can be determined by using one of the laws given here. Rule Pictorial Representation Right Hand Thumb Rule Imagine that you are holding the conductor in your right hand with the fingers curled around it. I..

Ohm's Law - It is found experimentally that the current I flowing through a conductor is directly proportional to the potential difference V across its ends, provided the physical conditions (temperature, mechanical strain, etc.,) remain constant. That ..

In the first compound hydrogen = 5.93% Oxygen = (100 -5.93) = 94.07% In the second compound Hydrogen = 11.2% Oxygen = (100 -11.2) = 88.88% In the first compound the number of parts of oxygen that combine with one part by mass of hydrogen In the second compound the number of parts by mass of oxyg..

According to Newton's law of gravitation, the force of attraction is directly proportional to the mass of the body. Consider two objects of mass m separated by a distance d, then the force between them is given by the relation Two Objects of Mass m Separated by a Distance d When the mass ..

>Oxygen is present 21% by volume in air. It supports life and combustion. It is added to air by photosynthesis and removed from air by respiration and combustion. Nitrogen is present 78% by volume in air. It is present in proteins, which are essential for life. It is removed from air by l..
