Which best explains the difference between a scientific theory and a scientific law?

• a

• b

Over time, scientists’ ideas about the structure of atoms have changed. Historic and current models of the atom are shown below. What must happen for the current model to continue to be accepted?

• a. Experimental evidence will need to continue to provide evidence for the current model.

• b. Scientific opinion will need to continue to support the current model of the atom.

• c. Scientists will need to build better microscopes so they can examine atoms more closely.

• d. Experimental evidence will need to provide evidence that the other models are not accurate.

One of Boyle's principles describes the relationship between pressure and volume with an equation, P1V1 = P2V2. What is this?
