Constants and Variables

Variables: Variables are the terms which can change or vary over time. It does not remain constant, unlike constant. For example, the height and weight of a person do not remain constant always, and hence they are variables. In an algebraic expression, x+y = . Aug 04,  · A constant variable, normally called a controlled variable, is the term for a variable that remains constant throughout an experiment, though other variables may change. An example is the water pressure for a faucet when measuring the amount of water released when the faucet is opened to various increments.

In this formula, 2 is a fixed number whereas the literal numbers d and r are not fixed because they depend upon the size of the circle.

For circles of different sizes, the values of d and r will be different. It follows from the above examples that in Algebra, we come across two types of symbols namely constants and variables as defined below.

Constant : A symbol having a constqnt numerical value is called a constant. OR The number before an alphabet variable is called a constant. Variable : A symbol which takes various numerical values is called a variable. OR The alphabet after a number constant is called a variable. Note: In some situations, literal numbers are also treated as constants. In such situations, it is presumed that the particular literal number will take a few fixed values.

Constant and Variable in Algebraic Expressions - Definition and Examples

The alphabet after a number (constant) is called a variable. In the formulas d = 2r; 2 is a constant whereas, r and d are variables. Note: In some situations, literal numbers are also treated as constants. In such situations, it is presumed that the particular literal number will take a few fixed values. Refractive index of glass is a constant = But refractive index is a variable constant and varies with the material. G is a universal constant and will never varry. The density of a substance is a constant at a constant temperature. Nov 21,  · Variables can be declared as constants by using the “const” keyword before the datatype of the variable. The constant variables can be initialized once only. The default value of constant variables are zero. A program that demonstrates the declaration of constant variables in C using const keyword is given as follows. Example. Live Demo.

The point of an experiment is to help the experimenter define the relationship between two parts of a natural process or reaction. The factors that can change value during an experiment or between experiments, such as water temperature, are called variables, while those that stay the same, such as acceleration due to gravity at a certain location, are called constants.

Experimental constants are values that do not change either during or between experiments. Many natural forces and properties, such as the speed of light and the atomic weight of gold, are experimental constants. In some cases, a property can be considered constant for the purposes of an experiment even though it technically could change under certain circumstances.

The boiling point of water changes with altitude and acceleration due to gravity decreases with distance from the earth, but for experiments in one location these can also be considered constants. The independent variable in an experiment is the variable whose value the scientist systematically changes in order to see what effect the changes have. A well-designed experiment has only one independent variable in order to maintain a fair test.

If the experimenter were to change two or more variables, it would be harder to explain what caused the changes in the experimental results. For example, someone trying to find how quickly water boils could alter the volume of water or the heating temperature, but not both. A dependent variable is what the experimenter observes to find the effect of systematically varying the independent variable. While an experiment may have multiple dependent variables, it is often wisest to focus the experiment on one dependent variable so that the relationship between it and the independent variable can be clearly isolated.

For example, an experiment could examine how much sugar can dissolve in a set volume of water at various temperatures. The experimenter systematically alters temperature independent variable to see its effect on the quantity of dissolved sugar dependent variable.

A controlled variable is a variable that could change, but that the experimenter intentionally keeps constant in order to more clearly isolate the relationship between the independent variable and the dependent variable. For example, an experiment examining the relationship between how much sunlight plants receive independent variable and how tall they grow dependent variable should make sure none of the other factors change.

The experimenter should control how much water the plants receive and when, what type of soil they are planted in, and as many other variables as possible.
