The energy of a system available to do work is called as:
- AGibbs free energy
- BHeat of formation
- CHeinsenberg uncertainty principle
- DHeat of vaporization
✓
Answer
- Gibbs free energy
Explanation:
The energy of a system available to do work is called as Gibbs free energy.
Heat required to rise one unit mass of a substance by 1 degree Celsius is known as Specific heat.
Heat absorbed or released during production of a substance from elements in their standard states is known as Heat of formation.
Heinsenberg uncertainty principle states that, "It is not possible to determine simultaneously the position and momentum of a moving microsopic particle (electron) with absolute accuracy".
Heat required to vaporize unit mass of a substance without changing its temperature at constant pressure is called Heat of vaporization.
