How is temperature expressed?

• A. Intensity of heat
• B. Volume of energy
• C. Conduction rate
• D. Pressure

Answer: (A)

Temperature expresses the intensity of heat, meaning how hot or cold a substance is. It’s a measure of the average kinetic energy of the particles in a material—the faster the particles move, the higher the temperature. This is why heat flows from hotter to cooler objects until they reach the same temperature. It’s not the volume of energy, since energy can exist in different forms and amounts without a direct one-to-one with temperature. It’s not the rate of heat transfer (conduction rate), which describes how quickly heat moves between objects, nor is it pressure, which concerns force per area and not how hot something is.
