Question 1Gas Turbine - Assistant Engineer

The correct answer is D) Increase volume. When thermal energy is added to a gas as it flows through the combustion section, the gas molecules gain kinetic energy, causing them to move faster and occupy a larger volume. This is a result of the Ideal Gas Law, which states that the volume of a gas is directly proportional to its temperature, assuming pressure and the amount of gas remain constant. The other options are incorrect because: A) Increasing the thermal energy would actually increase the pressure of the gas, not decrease it. B) Increasing the thermal energy would increase the volume of the gas, not decrease it. C) Increasing the thermal energy would increase the volume of the gas, not decrease the pressure.
