Who scientist verified law of constant proportion?
Joseph Proust.
What is meant by law of constant proportion and how is this law applied in experiment empirical formula of a compound?
The law of constant proportion states that a pure chemical compound always contains exactly the same proportion of elements by mass.This information, together with the atomic masses of the elements in the compound enable scientists to determine the formula of a compound.
The principle that two stimuli must differ by a constant proportion for their difference to be perceived is known as?
Weber's Law"Ernst Weber noted that for people to really perceive a difference, the stimuli must differ by a constant "proportion" not a constant "amount."
What is the rule of constant proportions?
The law of constant proportions, also called Proust's law, states that the elements in a compound are all present in a fixed proportion by weight, regardless of how the compound is prepared.
What in an expression of Dalton's law constant?
Dalton's law of constant proportion states that any sample of a chemical compound will have its constituent elements appearing in the same proportion by mass. Thus 8/9 of the mass of any sample of water will be oxygen and the remaining 1/9 will be hydrogen.

Who put forward the law of constant proportion?
This was an idea of John Dalton.

How does law of constant proportion applies in sea water?
The law of constant proportion, also known as the law of definite proportions, states that a chemical compound always contains its component elements in fixed ratio by mass. In seawater, this law applies to the dissolved salts, primarily sodium chloride, which consistently makes up about 3.5% of seawater by mass. Regardless of where seawater is sampled, the proportion of these dissolved salts remains relatively constant, demonstrating that the chemical composition of seawater is uniform despite variations in other components. This consistency is crucial for marine life and oceanic processes.
Law of variable proportion and law of returns to scale?
Under Law of variable proportion: only one variable input varies all other variable kept constant. Under Law of Return to Scale: All the variable inputs varies except the enterprise. Law of variable proportion is for short period; law of return to scale is for long period. Law of variable proportion shows the relationship if one variable input increase (eg: Labour) by keeping all other variable constant; total product and marginal product increase upto a certain point after that it will increase at a diminishing rate. it shows in three stage first increase then constant and then decrease. Law of return to scale shows the relationship between inputs and output at three different stages: 1. output increase more than inputs, 2. output and input are constant, 3. output is less than proportionate input.

Why is the law of constant composition important to chemistry?
It means that in any pure compound, the proportion of constituent elements (by mass) is a constant. This allows their chemical formulae to be determined.
What happens to strain as stress increases?
it also increases in the same proportion as stress. Stress equals strain times a constant, where the constant is Young's modulus. This is Hooke's Law
