Question

Heat required, to rise one unit mass of a substance by 1 degree Celsius, is known as ......................... .

• A. gibbs free energy
• B. heat of formation
• C. specific heat
• D. Heinsenberg uncertainty principle
• E. heat of vaporization

Answer 1

The correct option is C specific heat

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. Its formula is $\frac{Q}{m\times \Delta T}$.
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.
