Q
Q: Which of the following statements is true for an ideal gas?
Solution: For an ideal gas, the internal energy depends only on temperature, not on volume or pressure.
Steps: 5
Step 1: Understand what an ideal gas is. An ideal gas is a theoretical gas that follows certain rules, especially the gas laws.
Step 2: Know that the internal energy of a gas is the total energy contained within it, which includes kinetic and potential energy.
Step 3: Learn that for an ideal gas, the internal energy is primarily related to the temperature of the gas. This means that if you change the temperature, the internal energy changes.
Step 4: Recognize that the internal energy does not depend on the volume or pressure of the gas. This means that even if you change the size of the container or the pressure, the internal energy remains the same as long as the temperature is constant.
Step 5: Conclude that the statement 'For an ideal gas, the internal energy depends only on temperature, not on volume or pressure' is true.
