QUESTION:

A student prepares several samples of the same gas and measures their mass and volume. The results are tabulated as follows. Formulate a tentative law from the measurements.

                     

ANSWER:

Step 1 of 3

Scientific law and theory

A scientific law is a statement predicted based on experimental observations. It is a universal statement and is not usually revised as it is derived from experiments.

Scientific law describes the behavior of a system under particular conditions. It is used for future experiments on the systems.

A scientific law does not give any explanation or mechanism for the observation.

Scientific theory gives a detailed explanation of the behavior of a system. It is derived based on the scientific investigation on the experimental observation.

A theory is more complex than law and therefore is revised with discoveries and evidence.
