There is no variable, only a fixed number.
4
you CAN have a variable as an exponent.For example, look at the equation 2x =4. We know x=2
t=-4
The value of a variable is called the solution. You can determine if the solution is correct by solving for the variable by using the Distributive Property, and Inverse Operation. For an example: If x = 8, determine if it is a solution to 1x - 4 = 4 Replace x with 8. 1(8) - 4 = 4 1 * 8 = 8 8 - 4 = 4 4 = 4 Yes. 8 is a solution to the equation
The difference between permanent and variable gases is that variable gases change in response to activities in the environment, and permanent gases stay constant.
The variable gases are are those atmospheric gases whose concentrations vary through time. The variable gases are sometimes called the "minor gases" because they make up such a small percentage of the atmosphere by volume.. Carbon dioxide, methane, and water vapor are examples of variable gases.
water vapor
Water vapor
Solids have a definite volume and gases have a variable volume
Most abundant - Water Vapor
The Sun,Earth's orbit, the oceans,greenhouse gases,and dust.
change and no change
INDEPENDENT VARIABLE: gases introduced in the experimental chamber [Methane, Hydrogen and Ammonia). DEPENDENT VARIABLE: the outcomes of the experiment. CONTROL VARIABLE: the amount of gas introduced, the amount of water, the percentage of humidity in the chamber etc.
These gases are: nitrogen (78,084 %), oxygen (20,9476 %), water vapors (variable concentration), argon (0,934 %), carbon dioxide (0,0314).
There is no variable, only a fixed number.
The amount of water vapor in atmospheric gases is highly variable. More water vapor is found at lower altitudes, at 30,000 feet there is virtually no water vapor. There is a maximum of 4% water vapor in the atmosphere at any time.
