Jean-Baptiste, after studying the way heat flows through solid materials, discovers a ___
that says the rate of heat flow is proportional to the difference in temperature per centimeter, and he measures the constant of proportionality for several substances.

Sadi proposes the _ that substances become hot when rubbed because the pressure of the rubbing squeezes out a fiery bright substance he calls caloric.

James sets up an ___
in which he will carefully stir the water in an insulated container, keeping track of the force required to stir the water, and then measure any temperature rise in the water. He hopes to find out whether the energy of stirring can be transformed into heat.

What are the missing words?
Observation, Experiment, Law, Theory, Hypothesis

In science, a law is a statement that accurately describes the way a natural phenomenon occurs. Due to this, laws are created after testing a hypothesis several times. This matches Jean-Baptiste's proposal because his idea about heat flow has been tested by himself and others multiple times.

What is a hypothesis?

Different from a law, a hypothesis only states a possible explanation but this should be tested to become a law. This concept can be applied to Sadi because he only has an idea about heat flow but this has not been tested.

What is an experiment?

This is a procedure that aims at testing a hypothesis. This concept applies to James because he is carrying out an objective procedure to understand energy and heat.
