The process of comparing an unknown quantity to a standard known quantity is called calibration. This involves measuring the unknown quantity using a calibrated instrument or reference standard to determine its accuracy and reliability. Calibration ensures that measurements are consistent and accurate across different devices or instruments.

To compare an unknown quantity with a standard means to evaluate the unknown by measuring or examining it against a known or established reference point. This process helps to determine the value or characteristics of the unknown quantity in relation to the standard.
A beam balance measures mass by comparing the weight of an object to a known standard weight. When the two sides of the balance are equal, the weights are the same, indicating the mass of the object being measured. This method works based on the principle of equilibrium and the force of gravity acting on the objects.
Yes, you can compare a known quantity with an unknown quantity in making measurements by using the known quantity as a reference point to determine the value of the unknown quantity. This comparison can help provide a basis for estimation or calculation in determining the value of the unknown quantity.
An unknown or changing quantity is a variable in a mathematical equation or problem that is not fixed but can take different values. It is typically represented by a letter, such as x or y, and its value needs to be determined in order to solve the problem.
In mathematics, an unknown quantity represented by a letter is usually called a variable. Variables are used to symbolize values that can vary in an equation or formula. They allow us to write general expressions that can represent multiple possible scenarios.
