X-axis 1 cm = 10 marks Y-axis 2 cm = 10 c.f To reconstruct frequency distribution from cumulative frequency distribution. When we write, 'less than 10 - less than 0', the difference give the frequency 4 for the class interval (0 - 10) and so on. When we write 'more than 0 - more than..

Scales of Temperature - A reference scale with respect to which the temperatures can be measured is known as 'scale of temperature'. Various scales of temperatures are in use. Important scales of temperature are: Celsius scale Fahrenheit s..

Industrially, oxygen is manufactured from the air. The industrial method is based on a very simple principle known as Joule-Thomson effect. Air is first subjected to liquefaction (made liquid) and then to fractional distillation, to separate out oxygen from it. When a gas under pressure is relea..

Atomic Mass Unit Scale - The scale in which the relative atomic masses of different atoms are expressed is called atomic mass unit scale..

A thermometer is marked in ___ scale. => ohms or degrees Celsius or kilograms or liters..

The scale in which the relative atomic masses of different atoms are expressed is called atomic mass unit scale..

This scale of temperature was devised by Gabriel Fahrenheit (1687-1736). The lower and upper fixed points in this scale are considered as 32 0 F and 212 0 F respectively. The interval of 180 0 F is divided into 180 equal parts. Each part is known as 1 0 F. This is widely used by..

Lord Kelvin (1824-1907) devised this scale of temperature. Hence, this is called the Kelvin scale, and in this scale, temperature is expressed in Kelvin. In SI system, Kelvin is the unit of temperature. In this scale of temperature, zero of the scale..

The pH Scale - The strength of acids and bases can be expressed in terms of the concentration of the hydronium ions or hydroxyl ions in a solution. The concentration of hydronium ions in a solution can be expressed as moles of hydronium ions per litre of solution. This is expressed by a t..
