When steam is superheated, what happens to its temperature?

When steam is superheated, its temperature increases while the steam's volume remains constant initially. Superheating occurs after steam has already been produced and is heated further beyond the saturation temperature at the given pressure. As the steam is heated, the energy supplied increases the kinetic energy of the steam molecules, leading to a rise in temperature.

This process involves heating the steam at constant pressure, causing the temperature to increase without any accompanying increase in volume until it reaches a new equilibrium. It's important to understand that the superheated steam possesses higher energy compared to saturated steam and is more effective for transferring heat in many industrial processes.

The other options do not accurately describe the behavior of superheated steam since they either suggest a decrease in temperature or associate the temperature change with an increase in volume, which does not align with the principles of superheating.
