Q1ChemistryUnit 4: Chemical Thermodynamics

A system is said to be in thermodynamic equilibrium with Surrounding ¡f

Q2ChemistryUnit 4: Chemical Thermodynamics

Assertion The change in internal energy and change in heat enthalpy does not depend upon the path by which changes are brought in. Reason Both

\Delta U

and

\Delta H

are path independent as U and H are state functions.

Q3ChemistryUnit 4: Chemical Thermodynamics

Fill in the blank. Thermodynamics is the branch of science concerned with and their relation to energy and work.

Q4ChemistryUnit 4: Chemical Thermodynamics

The symbols

F . H . S . V_{m}

and

E^{o}

denote Helmholtz free energy, enthalpy, entropy, molar volume and standard electrode potential, respectively. The correct classification of the properties is:

Q5ChemistryUnit 4: Chemical Thermodynamics

Q6ChemistryUnit 4: Chemical Thermodynamics

f we plot volume of a certain mass of a gas against temperature at constant pressure, we get a straight line intersecting on the negative side at

-273^{\circ} C

which explains about absolute zero. This graph is known as:
