In scientific terms, temperature is defined as what?

• A. The color of the material
• B. The measure of the average kinetic energy of particles
• C. The volume of the substance
• D. The speed of sound in the medium

Answer: (B)

Temperature measures how much particle motion the system has on average. In kinetic theory, temperature is tied to the average kinetic energy of the particles: when you raise the temperature, the particles move faster and their average kinetic energy increases. That is why hotter objects have more vigorous molecular motion. This concept helps explain why heat flows from hotter to cooler objects until equilibrium is reached. Color has to do with light interacting with matter, not how fast its particles are moving. Volume is the amount of space the substance occupies, not its internal energy. The speed of sound depends on the medium’s properties like density and elasticity and only changes with temperature, rather than defining temperature itself. So the statement that temperature is the measure of the average kinetic energy of particles best captures what temperature represents.
