The correct answer is: theory.
A fact is a statement that can be proven to be true. A theory is a well-substantiated explanation of some aspect of the natural world, based on a body of facts that have been repeatedly confirmed through observation and experiment. A conclusion is a statement that follows from the evidence presented. An experiment is a procedure carried out to make a discovery, test a hypothesis, or demonstrate a known fact.
Avogadro’s hypothesis is a theory that states that equal volumes of all gases at the same temperature and pressure contain the same number of molecules. This hypothesis has been repeatedly confirmed through observation and experiment, and it is a fundamental principle of chemistry.
Here are some additional details about each option:
- Fact: A fact is a statement that can be proven to be true. For example, the statement “the Earth is round” is a fact. It can be proven to be true by observing the Earth’s shadow on the moon during a lunar eclipse, or by taking a picture of the Earth from space.
- Theory: A theory is a well-substantiated explanation of some aspect of the natural world, based on a body of facts that have been repeatedly confirmed through observation and experiment. For example, the theory of evolution is a well-substantiated explanation of how species change over time. It is based on a body of facts that have been repeatedly confirmed through observation and experiment.
- Conclusion: A conclusion is a statement that follows from the evidence presented. For example, if you observe that a ball is thrown into the air and it comes back down, you can conclude that the force of gravity is acting on the ball.
- Experiment: An experiment is a procedure 48.6-11.4 42.9-11.4 132.3-11.4 132.3s0 89.4 11.4 132.3c6.3 23.7 24.8 41.5 48.3 47.8C117.2 448 288 448 288 448s170.8 0 213.4-11.5c23.5-6.3 42-24.2 48.3-47.8 11.4-42.9 11.4-132.3 11.4-132.3s0-89.4-11.4-132.3zm-317.5 213.5V175.2l142.7 81.2-142.7 81.2z"/> Subscribe on YouTube
