Question
Like all substances, gases are made up of moving particles. The diagrams below show two pure samples of gas in identical closed containers. The colored balls represent the particles in each sample. square complete The mass of each particle is the same The particles in sample B have a lower average speed than the particles in sample A. Which particles have the lower average kinetic energy? the particles in sample A the particles in sample B nelther; the average kinetic energy is the same

Answer
The average kinetic energy of a particle in a gas is given by the equation:KE_avg = (1/2) * m * v^2where KE_avg is the average kinetic energy, m is the mass of the particle, and v is the average speed of the particle.From the information provided, we know that:- The mass (m) of each particle is the same in both samples.- The particles in sample B have a lower average speed (v) than the particles in sample A.Since the mass of the particles is the same for both samples, the average kinetic energy depends on the square of the average speed of the particles.Given that the particles in sample B have a lower average speed than those in sample A, and the mass is the same for both, the particles in sample B will have a lower average kinetic energy.Therefore, the answer is:the particles in sample B
