Science Questions For All Ages

Explanation
Hydrogen is the lightest element, because its atomic nunber is 1, which is the smallest number on the periodic table of elements

Explanation
The nucleus of an atom contains protons and neutrons. Protons have a positive charge, while neutrons have no charge. These particles are tightly packed together in the center of the atom, forming the nucleus. Electrons, on the other hand, are found outside the nucleus in electron shells. Therefore, the correct answer is "Protons And Neutrons."

Explanation
Albert Einstein is the correct answer because he is the famous scientist who discovered the theory of relativity. His groundbreaking work on the subject, published in 1905 and 1915, revolutionized our understanding of space, time, and gravity. The theory of relativity has had a profound impact on physics and has been confirmed by numerous experiments and observations. Einstein's contributions to science and his theory of relativity have made him one of the most celebrated and influential scientists in history.

Explanation
Albert Einstein is the correct answer because he is a famous scientist known for his theory of relativity and his equation E=mc². He is widely regarded as one of the greatest scientific minds in history and his work has had a profound impact on our understanding of the universe. Sir Isaac Newton is also a famous scientist, but he is best known for his laws of motion and his work in the field of physics and mathematics. However, Einstein's contributions to physics and his revolutionary ideas make him the more famous scientist in this context.

Explanation
Biology is the study of living organisms, including animals and plants. It focuses on their structure, function, growth, evolution, and distribution. This field of science explores various aspects of animals and plants, such as their anatomy, physiology, behavior, and interactions with their environment. Therefore, biology is the correct answer for the type of science that studies animals and plants.

Explanation
Argon is the correct answer because it is the most commonly used noble gas in traditional light bulbs. It is used to fill the bulb because it is an inert gas that does not react with the filament or other components inside the bulb. This helps to prolong the life of the bulb and maintain a stable environment for the filament to produce light.

Explanation
Scientists usually heat things up with a Bunsen burner. This is a common laboratory tool used in chemistry experiments to provide a controlled flame for heating substances. It allows scientists to adjust the intensity of the flame and provides a stable heat source. A cooker is not typically used in a laboratory setting, and the sun is not a practical option for controlled heating in most experiments.

Explanation
The correct answer is "The Ratio Of A Circles Circumference To Its Diameter". Pi is a mathematical constant that represents the ratio of a circle's circumference to its diameter. It is an irrational number, approximately equal to 3.14159, and is used in various mathematical and scientific calculations involving circles and curves.

Explanation
Tungsten (W) is classified as a transition metal. Transition metals are located in the middle of the periodic table and have properties that are intermediate between those of metals and nonmetals. Tungsten has a high melting point, excellent electrical conductivity, and is commonly used in the production of filaments in light bulbs and electrical contacts. It is also known for its hardness and resistance to corrosion, making it useful in various industrial applications. Therefore, the correct answer is transition metal.
