Final Answer:
Fact: Atoms are made up of protons, neutrons, and electrons.
Law: Energy can be neither created nor destroyed.
Fact: Water freezes at 0°C.
Hypothesis: If a piece of platinum is placed in acid, it will not react.
Step-by-step explanation:
Fact: "Atoms are made up of protons, neutrons, and electrons." This statement describes an established and verified piece of information about the composition of atoms, proven through extensive scientific evidence and experimentation.
Law: "Energy can be neither created nor destroyed." This statement represents a scientific law, specifically the law of conservation of energy. It is a fundamental principle in physics that has been consistently observed and supported by various experiments.
Fact: "Water freezes at 0°C." This statement describes an empirical observation about the freezing point of water under standard atmospheric pressure. It's a well-established fact based on repeated experimentation.
Hypothesis: "If a piece of platinum is placed in acid, it will not react." This statement proposes an idea or assumption about a potential reaction between platinum and acid. However, it hasn't been conclusively proven yet and would require experimentation or further observation to confirm its validity.
Each category—fact, law, and hypothesis—represents different levels of scientific certainty. Facts and laws are established through evidence and observation, while hypotheses are proposed explanations that need further testing to be confirmed or rejected.
