smell can not be measured but can be observed
You're probably looking for dependent variable.
Color is a physical property that can be observed but not measured quantitatively. It is a subjective experience that can vary based on individual perception.
One property of matter that can be observed and measured without changing its density is its color. The color of a substance can be determined visually or quantitatively using instruments like a spectrophotometer, without altering its density.
chemical property :D
something that is observed and can generally not be measured.
the dependent variable
One example of a condition that is observed and measured in an experiment is the temperature of a solution in a chemical reaction. Researchers can measure the temperature at different time points to investigate how it changes during the reaction, providing insights into the reaction kinetics and thermodynamics.
independent variable
One property of matter that can be observed and measured without changing the matter's identity is its mass. Mass is a measure of the amount of matter in an object and can be determined through various methods like weighing.
The variable observed during an experiment is called the dependent variable. It is the one being measured or tested in response to changes in the independent variable.
Dependent variable, according with my sources. :)
