Question

Why? When a sample of matter is heated, the particles speed up. But what does that mean? Are all the particles in a sample moving at the same speed? Do they all speed up equally? Does mass affect partide speed Two scientists, James Maxwell and Ludwig Boltmann. proposed an equation that could be used to predict the speeds of ideal gas particles (atoms or molecules) at any temperature. Their equation is based on watistics and thermodynamic relationships. It is used by chemists and physicists to predict properties of gases such as pressure and diffusion rates, and it can be used to predict rates of reactions involving gases. Model 1 - Helium at Different Temperatures Number of Particles out of 1 Million -- 100 °C - 100°C 500 C 0 500 1000 1500 3500 4000 4500 5000 2000 2500 3000 Particle Speed (m/s) 1. Consider the graph in Model 1. 4. What is the variable and unit of the x-axis? particle speed (m is) b. Particles of what substance are represented in the graph? Helium c. How many particles are represented in the graph? 3 million d. What temperatures are represented in the graph? - 100°C - - 100°C Maxwell-Boltzmann Distributions - - 500°C
why is the particles represented on the graph 3 million? (question c)
