Thermodynamics ...

A certain mass of gas is taken from an initial thermodynamic state A to another state B by process I and II. In process I the gas does 5 joules of work and absorbs 4 joules of heat energy. In process II, the gas absorbs 5 joules of heat. The work done by the gas in process II (see figure) is

Which of the following parameters does not charaterize the thermodynamic state of matter?

$$5.6\ litre$$ of helium gas at STP is adiabatically compressed to $$0.7\ litre$$. Taking the initial temperature to be $$T_{1}$$, the work done in the process is

"Heat cannot by itself flow from a body at lower temperature to a body at higher temperature" is a statement of the consequence of

Which of the following complexes has the least molar conductivity in the solution?

An ideal gas undergoes a quasi static, reversible process in which its molar heat capacity $$C$$ remains constant. If during this process the relation of pressure $$P$$ and volume $$V$$ is given by $${PV}^{n}=$$ constant, then $$n$$ is given by (Here $${C}_{P}$$ ad $${C}_{V}$$ are molar specific heat at constant pressure and constant volume, respectively):

What is the work done by $$0.2$$ mole of a gas at room temperature to double volume during isobaric process (take $$R=2 cal \ mol^{-1} K^{-1}$$)

One end of a $$0.25\ m$$ long metal bar is in steam and the other end is in contact with ice. If $$12\ g$$ of ice melts per minute, what is the thermal conductivity of the metal? Given cross-section of the bar $$= 5\times 10^{-4} m^{2}$$ and latent heat of ice is $$80\ cal/g$$.

Which heat is produced throughout the conducting wire?

Magnitude of Seebeck emf between the junctions does not depend on
