Boiling water represents a physical change as it undergoes a state change without altering its chemical composition.

The chemical symbol for gold is Au, derived from the Latin word 'aurum.'

The chemical formula for water is H2O, representing two hydrogen atoms and one oxygen atom.

The chemical name for common table salt is Sodium chloride (NaCl), composed of sodium ions and chloride ions.

The speed of light in a vacuum is approximately 300,000 kilometers per second, a fundamental constant in physics.

The control group establishes a baseline for comparison, helping researchers isolate and assess the impact of the independent variable in an experiment.

Isaac Newton is credited with formulating the laws of motion and the law of universal gravitation, fundamental principles in classical physics.

Physics is the branch of science that studies the behavior of matter and energy in the universe.

Mitochondria play a crucial role in cellular respiration, generating energy for the cell in the form of ATP.

Protons are subatomic particles carrying a positive charge and are found in the nucleus of an atom.

Photosynthesis is the process by which plants convert sunlight into energy, producing their own food in the form of glucose.

After forming a hypothesis, the next step in the scientific method involves conducting experiments to test and validate the proposed hypothesis.

A double-blind experiment is designed to eliminate bias by keeping both participants and researchers unaware of who is in the experimental and control groups, ensuring more objective results.

Albert Einstein proposed the theory of relativity, revolutionizing our understanding of space, time, and gravity.

The Heisenberg Uncertainty Principle is a fundamental concept in quantum mechanics, stating that certain pairs of properties cannot be precisely simultaneously known.

Charles Darwin proposed the concept of natural selection, explaining how species evolve and adapt over time.

The SI unit for measuring electric current is the Ampere (A), named after the French physicist André-Marie Ampère.
