The fundamental law of proportion, also known as the law of definite proportions or the law of constant composition, is a fundamental principle in chemistry that states that a chemical compound always contains the same elements in the same proportions by weight or by volume. This law is one of the cornerstones of modern chemistry and is based on the idea that chemical compounds are composed of fixed ratios of elements.

The discovery of the law of definite proportions can be traced back to the work of the French chemist Antoine Lavoisier in the late 18th century. Lavoisier was one of the pioneers of modern chemistry and is considered the "father of modern chemistry" due to his contributions to the development of the modern scientific method and the understanding of chemical reactions. Lavoisier's experiments showed that chemical reactions involve the transfer of atoms from one compound to another, and that the atoms of different elements can be combined in fixed ratios to form chemical compounds.

The law of definite proportions is important because it helps chemists understand the nature of chemical compounds and how they are formed. It also helps chemists predict the properties of chemical compounds and how they will behave in different reactions. For example, if a chemist knows the exact proportions of the elements that make up a particular compound, they can predict its melting point, boiling point, solubility, and other physical and chemical properties.

In addition to its importance in chemistry, the law of definite proportions has also had significant implications in other fields such as biology, geology, and materials science. For example, in biology, the law of definite proportions is used to understand the chemical makeup of different biomolecules and how they interact with each other. In geology, the law of definite proportions is used to understand the chemical composition of different minerals and how they form. In materials science, the law of definite proportions is used to understand the properties of different materials and how they can be manipulated to create new materials with specific properties.

In conclusion, the fundamental law of proportion, also known as the law of definite proportions or the law of constant composition, is a fundamental principle in chemistry that states that a chemical compound always contains the same elements in the same proportions by weight or by volume. This law is an important foundation of modern chemistry and has had significant implications in other fields such as biology, geology, and materials science.

## Law of definite proportions

For instance, there are two factors of production viz. It establishes a relation between two or more quantities and thus helps in their comparison. At this rate, how far could she run in 45 minutes? Proportion finds application in solving many daily life problems such as in business while dealing with transactionsor while cooking, etc. If the number of laborers is increased to 2, the new proportion between labour and land will be 2: 5. According toproportion, if two sets of given numbers are increasing or decreasing in the same ratio, then the ratios are said to be directly proportional to each other. According to the law of constant composition, all the samples present in the given compound would have the exact same elements in the same mass ratio. Based on the type of relationship two or more quantities share, the proportion can be classified into different types.

Condition or Causes of Applicability : There are many causes which are responsible for the application of the law of variable proportions. Here, a and b are any two integers. When an additional unit of a variable factor has to produce with the help of relatively fixed factor, then the marginal return of variable factor begins to decline. Fundamental rule of proportions means cross multiply. It can be increased as desired for a long period, being variable factors. He explains that to arrive from an equation which has fractions into the one without equation multiply the top of left side with the bottom of right side and equal it with bottom of left side multiplied with top of the right side.

Joan Robinson has put the argument that imperfect substitution of factors is mainly responsible for the operation of the law of diminishing returns. Hence, if a compound is made when Â¼ of one chemical is combined with the Â¾ of the other chemical, these proportions would always hold true irrespective of the amount of the chemicals that are added. If factors of production are to be combined in a fixed proportion, the law has no validity. Learn how to apply the fundamental rule of proportions just follow simple few steps.

## What is Proportion

Let us state the law of constant proportion. We know that 3 ounces of sugar are required for 6 ounces of cake. Here, total product increases at a diminishing rate. This means the same chemical compound will always contain the same elements in the same proportion irrespective of the source, method of preparation of the compound or amount of the compound. Calculate the mean and standard deviation of the simulated values. This starts from 8th unit.

This means that the composition of a compound does not depend on its source or its method of preparation. It is referred to as the law which states that when the quantity of one factor of production is increased, while keeping all other factors constant, it will result in the decline of the marginal product of that factor. Initially, this law, like many other laws, was criticized and debated. Proportion signifies the equal relationship between two or more ratios. The proportional-to symbol indicates that one expression changes in proportion to the other.

This tendency in the theory of production called the Law of Variable Proportion. In simple words, if one quantity increases, the other quantity also increases and vice-versa. Suppose land and labour are the only two factors of production. At this stage, any additional dose leads to positive nuisance because additional dose leads to negative marginal product. The ratio of the atoms contained in an element is given below as well.

From the top, multiply with bottom of right hand side and on the left hand side bottom, multiply with right hand side top and equate them. But in real practice factors are imperfect substitutes. Land is a fixed factor whereas labour is a variable factor. At point F average product is maximum and is equal to marginal product. This proportion of the masses remains constant for all the water molecules. We grow wheat on it with the help of variable factor i.

When variable factor is increased while keeping all other factors constant, the total product will increase initially at an increasing rate, next it will be increasing at a diminishing rate and eventually there will be decline in the rate of production. We should note that marginal product falls at a faster rate than the average product. This means that any given pure sample of the compound, irrespective of its source, will always contain the same kind of elements that are present in the same ratio by the mass. In this way proportions can be cross multiplied to arrive at an algebraic expression. However, of the three stages, a firm will like to produce up to any given point in the second stage only. In simple words, if one quantity increases, the other quantity also increases and vice-versa. He explains that to arrive from an equation which has fractions into the one without equation multiply the top of left side with the bottom of right side and equal it with bottom of left side multiplied with top of the right side.

## SOLUTION: The fundamental law of proportion

Therefore, this law holds good in all activities of production etc. When the fixed factor is used with variable factor, then its ratio compared to variable factor falls. A ratio is a mathematical expression written in the form of a:b, which expresses a What is Proportion in Math? The laws are thus often referred to as the laws of nature. He explains that to arrive from an equation which has fractions into the one without equation multiply the top of left side with the bottom of right side and equal it with bottom of left side multiplied with top of the right side. We see that total product, average product, and marginal product increases but average product and marginal product increases up to 40 units. A proportion is simply a statement that two ratios are equal.
