Two identical containers hold the same amount of carbon dioxide gas at constant pressure. Container A has a temperature of 220K and container B has a temperature of 670K. Which diagram correctly represents the distribution of molecular speeds for each container? Container A : Container B : Choose 1 answer: A D

The correct answer is **A**.<br /><br />Explanation: The distribution of molecular speeds in a gas depends on the temperature. At higher temperatures, molecules move faster on average, and the speed distribution becomes broader and shifts to higher values. Container B, being at 670K, will have a broader and more right-shifted speed distribution compared to Container A, which is at 220K.
