Final answer:
The average kinetic energy of the gas molecules doubles when the temperature increases from 50°C to 100°C. The correct answer is C.
Step-by-step explanation:
The average kinetic energy of a gas molecule is directly proportional to its temperature. According to the kinetic theory of gases, the average kinetic energy of gas molecules is directly proportional to the absolute temperature of the gas. Therefore, when the temperature of the gas increases from 50°C to 100°C, the average kinetic energy of the gas molecules doubles.
The average kinetic energy of a sample of gas increases but does not double when the temperature rises from 50°C to 100°C.
When a sample of gas increases in temperature from 50°C to 100°C, the average kinetic energy of the gas particles increases as well. According to the kinetic molecular theory, the average kinetic energy of a gas is directly proportional to its temperature in Kelvin. Therefore, when the temperature increases, the kinetic energy increases but does not double, since the relationship is not linear when considering degrees Celsius. The correct answer is d) increases but does not double.
