Each statement illustrates an example of qualitative data since there is no mention of any quantitative value.
<h3>What is meant by qualitative analysis? </h3>
The determination of non-numerical values which gives information about the species participating in a chemical reaction is called qualitative analysis. For example, analysing the products of the reaction or the time it takes for product formation.
This kind of analysis is not a reliable analysis like the quantitative analysis. In quantitative analysis, we have to analyze the amount of energy consumed or the amount of product formed.
No such analysis is made in the case of qualitative analysis which makes this kind of analysis less reliable and data-oriented.
Therefore, the statements mentioning which sample is heavier, which sample takes longer to react and which sample increased the temperature by 3 degrees are all statements which are examples of qualitative analysis.

These mechanoreceptors usually detect stimuli such as pressure, vibration, sound and touch from the internal and external environments.
Smell does not rely on mechanoreceptors but rather rely on olfactory receptors.
