Which of these is an example of conduction?
The answer is "A spoon in a cup of hot soup gets warmer."
When heat energy is transferred to objects, the kinetic energy of the particles changes. Heat energy always moves towards equilibrium, meaning that hotter objects transfer their heat to colder objects, and at an atomic level kinetic energy is transferred from faster moving particles to slower moving particles.
There are three types of heat transfer, conduction, convection, and radiation.
Conduction: transfer of heat between two atoms that are touching
Radiation: transfer of heat by electromagnetic waves (light) where particles are not touching
Convection: transfer of heat by the movement of fluids (liquid or gas) where hot particles rise and cold particles sink

You are doing an experiment where you pour different amounts of hot water into the 200mL of cold water and measure the final temperature. The purpose of a “control” in an experiment is to see what would happen if you did NOT do a test. If we are testing how the volume of warm water effects energy transfer, which cup is our control?

What is a conductor?
What is a conductor?
A conductor is a substance that transfers electric or heat energy easily.
Some types of matter transfer energy more easily than others. These substances are called “conductors.” An electrical conductor is a substance in which electrical charge carriers, usually electrons, move easily from atom to atom with the application of voltage. Conductivity, in general, is the capacity to transmit something, such as electricity or heat. Some examples of conductors are copper, steel, gold, aluminum, and brass. If a substance does NOT transfer energy efficiently, it is called an insulator. Some common insulators are: Glass, Air, Plastic, Rubber, Porcelain, and Wood.
