Which of the following is an example of a theory?
The theory has been supported and confirmed by the scientific community with evidence, so it is practical to just modify it
theory
True
law
Heat can cause matter to change form by accelerating particles, leading to a phase change or chemical reaction.
to ensure that the data is accurate and its interpretation is properly done
By knowing the radius of the Earth, one could calculate its circumference (C = 2 * Pi * r) and thus plan an expedition to h
new information is offered that doesn't fit the current theory and has been validated with repeated testing
Models in science can be a math equation, computer program, or a physical representation.
