Question

3. A gas expands from high pressure to low pressure at a constant temperature. The free energy of the system
a) increases b) decreases ut remains constant d) becomes zero
​

Answer 1

Explanation:

HEY MATE. .

We know that internal energy of a gas depends upon its pressure and temperature. Thus if a gas expands at constant temperature and pressure, than its internal energy remains same

Answer 2

Option c) remains constant

A gas expands from high pressure to low pressure at a constant temperature. The free energy of the system.

• We are aware that a gas's internal energy is influenced by its pressure and temperature. As a result, if a gas expands while maintaining a fixed temperature and pressure, its internal energy does not change.
• As the gas expands, the system's internal energy reduces. Because the Internal energy (U) is independent of the path, the work can be estimated in two different methods. The graph demonstrates that an adiabatic reversible process requires less labour than an isothermal reversible process.
• A shift in temperature happens when a gas is permitted to expand from a high-pressure to a low-pressure area. The Joule-Thomson effect is a name for this phenomenon. Even while it may change from one form to another, the universe's overall energy remains constant. The first rule of thermodynamics is this.
