Is gas independent variable?
We say that the pressure, p, is the dependent variable and that there are three independent variables; the amount of gas, n, the termperature, T, and the volume of gas, V. As the name implies dependent variables depend upon other quantities. On the other hand, independent variables have no such dependence.
What are examples of independent variables in science?
Example: Independent and dependent variables You design a study to test whether changes in room temperature have an effect on math test scores. Your independent variable is the temperature of the room. You vary the room temperature by making it cooler for half the participants, and warmer for the other half.
Which gas property is the independent variable?
The volume will serve as the independent variable, which is changed by the researcher. The pressure will be the dependent variable, whose response is measured.
What are the four variables used to describe gases?
In this activity, you will explore four variables that quantify gases—pressure (P), volume (V), temperature (T), and moles (n) of gas. These four variables can be related mathematically so that predictions about gas behavior can be made.
Is temperature independent or dependent?
Imagine you are heating up a pot of water on the stove. You can move the dial to different heat levels; this is an independent variable. However, the temperature in the pot of water is a result of you turning a dial so you can’t control it directly. This makes the temperature of the water a dependent variable.
Is temperature an independent variable?
An independent variable is one that is unaffected by changes in the dependent variable. For example when examining the influence of temperature on photosynthesis, temperature is the independent variable because it does not dependent upon photosynthetic rate.
Can you have 2 independent variables?
There are often not more than one or two independent variables tested in an experiment, otherwise it is difficult to determine the influence of each upon the final results. There may be several dependent variables, because manipulating the independent variable can influence many different things.
What are examples of independent?
The definition of independent is someone or something that is free from the influence or control of another. An example of independent is someone who lives on their own and supports themself. Of or relating to the 17th-century English Independents. Not relying on others for support, care, or funds; self-supporting.
What are the variables that identify a gas?
Volume, Temperature, Pressure, and Amount. All gases must be enclosed in a container that, if there are openings, can be sealed with no leaks.
What can be used to describe a gas?
Because most gases are difficult to observe directly, they are described through the use of four physical properties or macroscopic characteristics: pressure, volume, number of particles (chemists group them by moles) and temperature.
Is sunlight independent or dependent?
In this case, the number of hours of sunlight is the independent variable and the height of the plant is the dependent variable, because the change in the height depends on the hours of sunlight, not the other way around.
