FAQs: Frequently Asked Questions about Everyday Science

Q: What is the study of living organisms called?

A: The study of living organisms is known as biology. This vast field encompasses everything from the smallest bacteria to the largest whales, exploring their structure, function, growth, evolution, and distribution.

Q: Why do stars twinkle?

A: Stars appear to twinkle due to the Earth’s atmosphere. As light from a distant star travels through the atmosphere, it passes through layers of air with different temperatures and densities, causing the light to bend or refract, which makes the star appear to twinkle.

Q: What is the boiling point of water in Celsius and Fahrenheit?

A: The boiling point of water is 100°C (Celsius) and 212°F (Fahrenheit) at standard atmospheric pressure. This is a fundamental concept in thermodynamics and is a key reference point for both temperature scales.

Q: What are the main components of air?

A: The main components of Earth’s atmosphere are nitrogen (approximately 78%), oxygen (approximately 21%), and argon (about 0.9%). The remaining fraction consists of various trace gases, including carbon dioxide, neon, and helium.

Q: What is the function of red blood cells?

A: The primary function of red blood cells (erythrocytes) is to transport oxygen from the lungs to the body’s tissues. They contain a protein called hemoglobin, which binds to oxygen and carries it throughout the circulatory system.

Q: Why is the sky blue?

A: The sky appears blue due to a phenomenon called Rayleigh scattering. As sunlight enters the Earth’s atmosphere, molecules of gas and particles scatter the light. Blue light has a shorter wavelength and is scattered more effectively than other colors, making the sky appear blue.

Q: What is the difference between mass and weight?

A: Mass is the amount of matter in an object, which remains constant regardless of its location. Weight is a measure of the gravitational force exerted on an object. Therefore, an object’s weight can change depending on the gravitational field it is in, while its mass stays the same.

Q: What is the speed of light?

A: The speed of light in a vacuum is approximately 299,792,458 meters per second, or about 186,282 miles per second. This is the fastest speed at which all known physical objects can travel, and it is a fundamental constant in physics.

Q: What is the purpose of a vaccine?

A: A vaccine is a biological preparation that provides active acquired immunity to a particular infectious disease. It stimulates the body’s immune system to recognize and fight off specific pathogens, protecting the individual from future infections.

Q: How does a rainbow form?

A: A rainbow is a meteorological phenomenon that is caused by reflection, refraction, and dispersion of light in water droplets resulting in a spectrum of light appearing in the sky. It takes the form of a multicoloured circular arc.
