Question 1.16 - Chemistry: Molecular Nature Of Matter And Change

Question

Describe the essential features of a well-designed experiment.                                                                              

Step-by-Step Solution

Answer

Answer

 

A well-defined experiment should be carried out in a controlled manner and include two variables. A change in one variable is observed with respect to the other variable. Quantities used in the experiment can have more than one particular value accordingly.

Definition of experiment and its relationship with hypothesis

In general, an experiment includes steps that are performed in a sequential manner that helps in testing a hypothesis. 

Thus, it can be considered the link between our hypothesis studies with the natural hypothesis. 

 

The scenario of hypothesis and experiment can be shown                                                                       

Scenario of hypothesis and experiment

 

It should be noted that the result of an experiment performed cannot be changed according to the hypothesis. However, the hypothesis can be altered with respect to the experimental result.

Essential feature of well-defined experiment

A well-defined experiment should be carried out in a controlled manner and include two variables, among which change in one variable is observed with respect to the other variable. Quantities used in the experiment can have more than one particular value accordingly.

The experiment is undertaken if the result is consistent not only for the one who depicted it but for the latter experiment.
