Question

The enthalpy and internal energy are the function of temperature for

• A. All Gases
• B. Steam
• C. Water
• D. Ideal Gas

Hint:

For ideal gases, both internal energy and enthalpy depend only on temperature, unlike real gases or liquids where other factors may also influence them.

Answer 1

The Correct Option is D

Step 1: Understand the relationship between enthalpy, internal energy, and temperature.
For an ideal gas, both enthalpy and internal energy are functions of temperature only, because ideal gases have no interactions between molecules and their behavior is completely described by temperature.
Step 2: Identify the correct option.
For ideal gases, the internal energy and enthalpy are both only dependent on temperature.
For other substances like steam or water, additional factors like pressure and volume affect these properties.
