Which of the following is an example of a scientific theory?
a.) a prediction that a particular substance will float in water
b.) experimental results which show that changing the temperature of a chemical will affect its rate of decay
c.) an explanation of how light is created by the movement of electrons
d.) more than one of the above

D.) more than one of the above

A.) a prediction that a particular substance will float in water  

B.) experimental results which show that changing the temperature of a chemical will affect its rate of decay

Explanation:

A scientific theory can be describe as the proposed statement for the cause of a particular natural phenomena or event. This is based upon the implementation of a suitable scientific methodology and observed data.

Among the options given, A.) a prediction that a particular substance will float in water  

B.) experimental results which show that changing the temperature of a chemical will affect its rate of decay. are correct this is because of the fact that they can be verified on the basis of implementation of a suitable scientific procedure. The observations can be useful for answering the cause of a phenomena.
