Causes of law of variable proportions
the average variable cost curve and average cost curve are u- shaped because of the law of variable proportions.
A nonchemical combination of two or more substances in variable proportions is a mixture.
what is relationship between change in input and output. In the return's to scale (long term concept) all the factor are variable but in the variable proportions are some factor variable and some factors are fixed.
The law of definite proportions was developed by Joseph Proust in 1806.
Law of definite proportion, sometimes also called the law of constant composition.
The law of multiple proportions was proposed by John Dalton in 1804; today this law has not a general validity.
The law of definite proportions states that all chemical compounds have constant proportions of their components.
The Law of Multiple Proportions was proposed by John Dalton.
The law of multiple proportions can be partly explained by the idea that whole atoms of the same element combined to form compounds. Examples of the law of multiple proportions are CO and CO2.
Dalton\'s principle of compounds supports the law of definite proportions.
The Law of Multiple Proportions was developed by John Dalton based on the Law of Definite Proportions, was part of what laid the groundwork for his atomic theory, and for the basis of chemical formulas for compounds.English chemist John Dalton
