Science Concepts Quiz

I can be measured using a thermometer, and I affect the movement of molecules. When I increase, molecules move faster, and when I decrease, they slow down. I can be expressed in Celsius, Fahrenheit, or Kelvin. What am I?

I travel in waves and carry energy through space. I am part of the electromagnetic spectrum, with wavelengths that vary from very short to very long. You can’t see me, but I can heat you up or help you see in the dark. What am I?

I am the lowest possible temperature, where atoms stop moving entirely. I exist at 0 on the Kelvin scale, but you’ll never find me in nature. I represent a theoretical state where all molecular motion ceases. What am I?

I am the standard system used worldwide, where all units are based on seven fundamental quantities. My base units help measure length, mass, time, temperature, electric current, amount of substance, and luminous intensity. What am I?

I am a unit of power, often used to measure energy conversion. I am equal to one joule per second and can describe the rate at which energy is used or produced. You’ll find me when you calculate how much energy an electric device consumes. What am I?

I am stored in the bonds of atoms and molecules, ready to be released through reactions. I power everything from batteries to your body’s metabolism. When I’m released, I can create heat, light, or motion. What am I?

I am the energy of motion, and I depend on an object’s mass and speed. The faster I move, the more of me there is. You can see me in a rolling ball or a speeding car. What am I?

I am the energy transferred from one object to another due to a temperature difference. You feel me when you touch something hot or cold, and I can move through conduction, convection, or radiation. What am I?

I am the process where heat is transferred through fluids like air or water. I occur when warm particles rise and cooler ones sink, creating a circular flow. You can find me in boiling water or the movement of air in the atmosphere. What am I?
