Answer: Fact: A set of data or observations  that have been shown to be  accurate through multiple trials.
Hypothesis: A proposed explanation for  an occurrence based on  available data, observations, or evidence.
Law: A well-supported explanation  of all the evidence related to  a natural phenomenon.
Theory: A description of a natural  phenomenon that is always  observed to occur under  specific conditions
Explanation:
Fact: A set of data or observations that have been shown to be  accurate through multiple trials.
A fact can be define as the data or information that is obtained through the process of experimentation. This can be generated after the repetition of the experimental procedures so as to obtain concordant data which can be useful in framing the outcome of the experiment.
Hypothesis: A proposed explanation for an occurrence based on available data, observations, or evidence.
A hypothesis is a proposed explanation for the occurrence of a phenomena. This is based upon the data, observations and limited evidences that are required to be verified using experimental procedures. 
Law: A well-supported explanation of all the evidence related to  a natural phenomenon.
A law is the verified explanation of the factors responsible for the cause of natural phenomena by repetitive experimental procedures. The law cannot be changed on the basis of new discoveries and facts. It remains static.
