The Big Quiz On General Science

Salvador Luria is credited with inventing the most common bacterial medium. Luria was a prominent Italian-American microbiologist who made significant contributions to the field of bacteriophage genetics. He developed the Luria-Bertani (LB) medium, which is widely used in laboratories to culture and grow bacteria. The LB medium provides all the essential nutrients required for bacterial growth, making it a versatile and widely adopted medium in microbiology research.

The unit of measure called clo is used to determine the value of thermal insulation of clothing. It quantifies the ability of clothing to resist heat transfer, with higher clo values indicating better insulation. This measurement is important in determining the effectiveness of clothing in keeping the body warm in different environmental conditions.

The freezing point of water in the Kelvin scale is 273.15. In the Kelvin scale, 0 Kelvin represents absolute zero, the point at which all molecular motion ceases. Therefore, the freezing point of water, which is the temperature at which water changes from a liquid to a solid state, is 273.15 Kelvin.

Mars takes approximately 1.88 years to complete one revolution around the Sun. This is known as its orbital period or its year. The length of Mars' year is significantly longer than Earth's, which takes approximately 365.25 days to complete one revolution. The longer orbital period of Mars is due to its larger distance from the Sun compared to Earth.

The Beaufort scale is a measurement system used to determine the intensity of wind. It categorizes wind speeds into different levels based on their effects on the environment, such as the movement of leaves, the behavior of waves, and the damage caused to buildings and trees. This scale is widely used in meteorology, aviation, and maritime industries to provide a standardized way of describing and comparing wind speeds.

Absolute zero temperature is the lowest possible temperature that can be reached, where all molecular activity ceases. It is the point at which all substances have minimal internal energy. In the Fahrenheit scale, absolute zero is approximately -459.69 degrees F. This extremely low temperature is equivalent to -273.15 degrees Celsius or 0 Kelvin. At absolute zero, atoms and molecules have no kinetic energy, and all motion stops, making it impossible to reach a lower temperature.

Absolute zero is the lowest possible temperature that can be reached, where all molecular motion ceases. It is the point at which all substances have minimal internal energy. In the Celsius scale, absolute zero is equal to -273.15 degrees Celsius. Therefore, the correct answer is -273.16 degrees Celsius, as it is the closest approximation to absolute zero in the given options.

One pound is equal to 16 ounces. Since a dime weighs 2.268 grams, we can calculate the number of dimes in one pound by dividing the weight of one pound (453.592 grams) by the weight of one dime. Therefore, there are approximately 200 dimes equal to one pound in weight.

John H. Van Vleck was awarded the Nobel Prize in 1977 for his contributions to the understanding of the behavior of electrons in magnetic materials. His area of expertise is in magnetism, as he made significant advancements in the field by developing mathematical models to explain the behavior of electrons in magnetic materials. His work laid the foundation for the understanding of magnetism and its applications in various fields such as technology and materials science.

12.36 microseconds is the equivalent to one unit of Radar Range Mile.

Spontaneous combustion refers to the ignition of materials stored in bulk without an external ignition source. It occurs when the heat generated by the material's own chemical reactions reaches a critical point, causing it to catch fire. This phenomenon is commonly observed in materials with high flammability, such as oily rags, hay, or coal dust. The heat generated by the material's oxidation process builds up over time, eventually leading to ignition.

Angstrom is the correct answer because he was a Swedish physicist and astronomer who made significant contributions to the field of spectroscopy. He developed a unit of length, known as the angstrom, which is commonly used to measure wavelengths of light and other electromagnetic radiation. Angstrom's work laid the foundation for the analysis of the light spectrum, which is crucial in understanding the properties of light and its interaction with matter.

Einstein submitted his paper containing the correct field equations of general relativity in 1915. This was a groundbreaking achievement in the field of physics, as it provided a new understanding of gravity and the curvature of spacetime. The theory of general relativity revolutionized our understanding of the universe and has since been confirmed by numerous experiments and observations.

The correct answer is Illinois because it was in this state that the first self-sustaining nuclear chain reaction took place in 1942. This historic event occurred at the University of Chicago as part of the Manhattan Project, which was a research effort to develop atomic weapons during World War II. The successful demonstration of a controlled nuclear chain reaction paved the way for the development of nuclear power and the atomic bomb.

Pluto takes approximately 248 years to complete one revolution around the Sun. This is because Pluto's orbit is highly elliptical and elongated, causing it to have a longer orbital period compared to other planets in our solar system. It takes almost 248 Earth years for Pluto to travel around the Sun once, making it the longest orbital period among the known planets.
