The Correct Answer and Explanation is:<\/mark><\/strong><\/p>\n\n\n\n

The correct answer is A. Neither Technician A nor B<\/strong>.<\/p>\n\n\n\n

Here is a detailed explanation of why both technicians are incorrect.<\/p>\n\n\n\n

Analysis of Technician A’s Statement<\/strong><\/p>\n\n\n\n

Technician A claims that vapor has a fixed volume that remains the same when temperature increases. This statement is fundamentally incorrect. One of the defining properties of a substance in the gaseous state, such as a vapor, is that it has neither a fixed volume nor a fixed shape. A vapor will always expand to fill the entire volume of whatever container it occupies. The concept of a fixed volume applies to liquids and solids, but not to gases.<\/p>\n\n\n\n

Furthermore, the relationship between the temperature and volume of a gas is described by the gas laws, specifically Charles’s Law. This law states that at a constant pressure, the volume of a gas is directly proportional to its absolute temperature. This means that if the temperature of a vapor increases, its molecules gain kinetic energy, move faster, and spread farther apart. Consequently, the volume of the vapor will increase, assuming it is in a flexible container or a system where pressure is kept constant. Therefore, Technician A’s statement is scientifically inaccurate.<\/p>\n\n\n\n

Analysis of Technician B’s Statement<\/strong><\/p>\n\n\n\n

Technician B claims that decreasing the temperature of a vapor will increase its pressure. This statement is also incorrect. The relationship between the temperature and pressure of a gas at a constant volume is described by Gay-Lussac’s Law. This law states that the pressure of a gas is directly proportional to its absolute temperature.<\/p>\n\n\n\n

This means that if you decrease the temperature of a vapor, its pressure will also decrease. Temperature is a measure of the average kinetic energy of the molecules. When the temperature is lowered, the molecules slow down. These slower-moving molecules will collide with the walls of their container less frequently and with less force. This reduction in the rate and force of collisions results in a decrease in pressure. Technician B’s statement describes the opposite of this established physical principle.<\/p>\n\n\n\n

Since both technicians have made statements that contradict the known laws of gas behavior, neither of them is correct.<\/p>\n\n\n\n
