What is the principle used in the separation of mixtures?
Answer: The principle used in the separation of a mixture employs a special property of one of the components of the mixture. For example, iron pieces mixed with sand can be separated using a magnet as iron gets attracted towards the magnet.
What is the basic principle of calorimetry?
The principle of calorimetry (or principle of mixtures) states that for an insulated system, heat energy lost by the hot body is equal to the heat energy gained by the cold body. Note: Heat transfer occurs until both the bodies attain the same temperature(t).
What is the other name of principle of calorimetry?
the law of conservation energy
The principle of calorimetry indicates the law of conservation energy, i.e. the total heat lost by the hot body is equal to the total heat gained by the cold body….Also, Read.

On what does the accuracy of the method of mixtures depend?
The biggest factor in the accuracy of your results will be the quality of calorimeter you are using. Calorimeters are used to measure the heat transfer from a sample into a container of water.
What is the principle used in the separation of mixtures Class 9?
Such mixtures are separated by centrifugation. The principle is that the denser particles are forced to the bottom and the lighter particles stay at the top when spun rapidly.
What is the principle of calorimetry Brainly?
The principle of calorimetry states that the hear gained by the cold body must be equal to the heat lost by hot body, provided there is no exchange of heat with the surrounding. The principle is a consequence of the law of conservation of energy.
What is the principle of calorimeter Class 11?
Principle of Calorimetry is heat lost by one body is equal to the heat gained by another body. The Device which measures Calorimetry is known as Calorimeter.
What is calorimetry in biochemistry?
Calorimetry is a general term referring to the measurement of the quantities of heat evolved or absorbed in physical or chemical processes. Since most chemical processes do occur with measurable heat effects, calorimetry can be used to study a wide variety of chemical systems.
What is the method of mixtures and how it used to determine specific heat?
A method of determining the heat of fusion of a substance whose specific heat is known, in which a known amount of the solid is combined with a known amount of the liquid in a calorimeter, and the decrease in the liquid temperature during melting of the solid is measured.
What are the possible sources of error of the mixture method?
Drafts, temperature changes, light/dark differences, and electrical or magnetic noise are all examples of environmental factors that can introduce random errors. Physical errors may also occur, since a sample is never completely homogeneous.
What is the principle of chromatographic method Class 12?
The basic principle of chromatographic technique is based on the differential migration of the individual components of a mixture through a stationary phase under the influence of moving phase. The stationary phase may be a porous solid (such as silica, alumina, etc.)
