Questions & Step-by-Step Solutions
In an ideal gas, the average kinetic energy of a molecule is directly proportional to:
Correct Answer: absolute temperature (T)
Step 1: Understand what an ideal gas is. An ideal gas is a theoretical gas that follows certain rules, especially that its molecules are in constant random motion.
Step 2: Learn about kinetic energy. Kinetic energy is the energy that an object has due to its motion.
Step 3: Know that in an ideal gas, the molecules move faster when the temperature increases.
Step 4: Recognize that temperature is measured in Kelvin, which is the absolute temperature scale.
Step 5: Realize that the average kinetic energy of the gas molecules increases as the absolute temperature (T) increases.
Step 6: Conclude that the average kinetic energy of a molecule in an ideal gas is directly proportional to the absolute temperature (T).
