Which of the following behaviors exemplifies the concept of dietary moderation? Eat only unprocessed plant products. If breakfast was high in fat and sodium, plan to eat something relatively low in fat and sodium for dinner. Eat only "good" foods such as fruits and vegetables and avoid the "bad" foods such as steak and ice cream. Choose several different foods from each food group throughout the day.

Physics 335 Credit: Michael Loverude III. Pressure in the particulate model In a particulate model of gases, we can account for the pressure by considering collisions of gas particles with the container walls. Specifically, the value of the pressure is given by the product of the following two quantities: • the average magnitude of the change in momentum of a particle in a collision with a wall • the number of particles colliding with the wall per unit time and unit area A. Two tanks of equal volume each contain one mole of the same ideal gas. The gas in box B is at a higher temperature than the gas in box A. i. Is the average speed of the particles in box B greater than, less than, or equal to the average speed of the particles in box A? A B Ideal gas (1 mole) Ideal gas (1 mole) Cold Hot ii. Is the average change in momentum of one gas particle in a single collision with a wall in box B greater than, less than, or equal to the corresponding quantity in box A? Explain. iii. On average, will a single particle collide with a wall more, less, or equally often in box B than in box A? Explain. (Hints: Is the distance between opposite walls different? Is the average speed of the particles different?) Is the number of particles colliding with a wall per unit time and unit area in box B greater than, less than, or equal to the number of particles colliding with a wall per unit time and unit area in box A? Explain. iv. Use your answers to parts ii and iii above to predict whether the pressure in box B is greater than, less than, or equal to the pressure in box A. Is your answer consistent with the ideal gas law? 3
