Question 313General Subjects - Assistant Engineer
70% to passIf Charles' law describes the relationship between the temperature and volume of ideal gases, what statement is true?
AIf the pressure remains constant, the volume of a given mass of gas is inversely proportional to its temperature.
BIf the temperature remains constant, the volume of a given mass of gas is inversely proportional to its pressure.
CIf the pressure remains constant, the volume of a given mass of gas is directly proportional to its temperature.
DIf the temperature remains constant, the volume of a given mass of gas is directly proportional to its pressure.
AI Explanation
The correct answer is C) If the pressure remains constant, the volume of a given mass of gas is directly proportional to its temperature. This is correct because Charles' law states that for a fixed mass of an ideal gas kept at constant pressure, the volume is directly proportional to the absolute temperature. As the temperature of the gas increases, the volume also increases proportionally. The other options are incorrect because they do not accurately describe the relationship between temperature, volume, and pressure as defined by Charles' law.
