-
A. Temperature
-
B. Volume
-
C. Pressure
-
D. Heat content
Explanation
It is the total heat content of a system when the pressure is constant.
It helps us understand energy changes in chemical reactions.
-
A. Work (W)
-
B. Enthalpy (ΔH) or Gibbs Free Energy (ΔG)
-
C. Internal Energy (ΔU)
-
D. Entropy (ΔS)
Explanation
At constant pressure, heat change is measured as enthalpy (ΔH).
At constant temperature and pressure, the useful energy available to do work is measured as Gibbs Free Energy (ΔG).
گیس کا وہ قانون جس میں پریشر کو مستقل رکھا جاتا ہے ______ کے نام سے جانا جاتا ہے؟
-
A. Boyle's Law
-
B. Dalton's Law
-
C. None of these
-
D. Charles' Law
Explanation
- Charles's Law:
- Volume () is directly proportional to temperature () at constant pressure.
- Formula: .
- Boyle's Law:
- Pressure () is inversely proportional to volume () at constant temperature.
- Formula: .
- Ideal Gas Law:
- Combines Charles's and Boyle's Laws. Relates pressure, volume, temperature, and moles of gas.
- Formula: , where is the gas constant and is the number of moles.
