- Activity A: Temperature and diffusion Get the Gizmo ready: . Click Reset (2). Set the Wall to 100%. x in A y in A Introduction: In this Gizmo, temperature is measured on the Kelvin scale. On this scale, 0 K represents absolute zero, the coldest possible temperature. Water freezes at 273.15 K (0 °C), and water boils at 373.15 K (100 °C). Question: How does temperature affect the rate of diffusion? 1. Observe: Set the temperature (Temp.) to 100 K, and press Play. Observe the motion of particles. Click Reset. Then set the temperature to 600 K, click Play, and observe. How does the temperature of the gas relate to the motion of the particles? The temperature of a gas is a measure of the average kinetic energy of a set of particles. Kinetic energy (KE) depends on the velocity and mass of the particles (KE = mv² / 2). 2.
