Temperature is a measure of what?

Temperature is a measure of what?

• A. Humidity.
• B. The average kinetic energy of the particles.
• C. Air pressure.
• D. Dew point.

Answer: (B)

Temperature is a measure of the average kinetic energy of the particles in a system. When you heat something, its molecules move faster on average, raising their kinetic energy, which a thermometer detects as a higher temperature. Humidity describes how much water vapor is present, not how fast molecules are moving. Air pressure is the force exerted by air on surfaces, related to density and temperature but not the temperature itself. Dew point is the temperature at which air becomes saturated and condensation begins, telling you about moisture levels rather than the mean molecular motion. So temperature directly reflects the average kinetic energy of the particles, making it the best answer.
