A variable is something that is being changed purposely, to observe what effects changing it has on the substance, reaction, etc. For example, if one were to test the effects of less or more water on plants, the amount of water could be called a variable.
When scientists talk about a variable, generally this is an algebraic reference to a term in an equation which can have different, or varying values; to use a simple example, in the equation x = 2y, the value of 2 is always the same, but x and y can have infinitely many values for which that equation remains valid (for example, if x = 4 then y = 2, if x = 300 then y = 150, etc.).
SO. There are two types of variables. The independent variable, and the dependent variable.
Independent Variable: Also known as the IV.
What YOU change. Think of it as I change it. "I"
Dependent variable.
What you are going to find out from the experiment.
Hope i helped :)
I'm not sure about in science, but in computing terms it is somthing that changes, such as time, - apposed to the codes to start up a computer(which are always the same - unless altered of course ). e.g. In everyday terms- the weather or amount of reproduction in the world.
A variable is something that may be changed or manipulated during an experiment. It can also represent an "unknown" quantity. A controlled variable is something that you can keep constant.
somehing that can change ex. you health it all matters about what u eat how much u exersize so on. its something that can change because of something else
In chemistry, variables are outside forces that can be manipulated to alter experiments. Variables include temperature, light, time, and volume.
when refering to the controlled variable... a control for a chemistry lab or experiment refers to constant state of a variable, item, substance, pressure, etc. Nothing about the variable can change through out the entire experiment.
A controlled chemistry is authoritarian rule over science departments a controlled chemical reaction is when a chemical reaction can be ceased easily by either removing a reactant or changing conditions such as temperature or PH.
You need to be an university graduate, chemistry department (3 years + 2 years specialization in analytical chemistry); but the situation may be variable in different countries. But it is important to mention that this job is important and requires hard work and study if you want to be serious.

language is different, filipino chemistry is chemistry of filipine, foreign chemistry is chemistry of that country

A collective variable is defined as a reaction coordinate in a abstract one dimensional coordinate. Collective variables are used in chemistry.
The dependent variable is located on the Y axis. The independent variable is located on the X. The dependent variable changes in response to the independent variable changing, while the independent variable is the variable that is purposefully changed in an experiment. It's easy to remember -I-ndependent, -I- change.
In math, it is the number that comes before the variable, such as x. In chemistry, it is the number that comes before the chemical formula.
Well I think that the answer is force and area. <3

what you change and dependent variable is what you measure. :) Also, generally the independent variable goes on the x axis of any given graph, while the dependent goes on the y axis (except for specific types of graph characterized by their shape, such as rate of reaction graphs in chemistry)
It means a change in. For example if you had Delta(y) that would mean a change in Y values in respect to another variable

what in 1st order?? if you are asking about 1st order chemical equation then there will be only one variable with power 1.
A variable is an unknown, so algebra equations contain them. there are lots of different ways you can see a variable though whether it be in chemistry physics , business or just a math course. They can be huge equations or just simple ones. But there will be an unknown. Usually denoted as a "x" or "y" etcFor example 4x+3y^2+10x-2y+8x
