Second Law of Thermodynamics

What is the entropy change (in ${\mathrm{JK}}^{-1}{\mathrm{mol}}^{-1}$ ) when one mole of ice is converted into water at  $0°\mathrm{C}$? (The enthalpy change for the conversion of ice to liquid water  $6.0\hspace{0.17em}\mathrm{kJ}\hspace{0.17em}{\mathrm{mol}}^{-1}\mathrm{\hspace{0.17em}}\mathrm{at}\mathrm{\hspace{0.17em}}0°\mathrm{C}$)

According to second law of thermodynamics :

What is the Kelvin Planck Statement

An ideal gas heat engine operates in Carnot cycle between $227 °\mathrm{C}$ and $127 °\mathrm{C}$. It absorbs $6\times 10^4$ cal of heat at high temperature. Amount of heat converted to work is:

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

Write the statement of second law of thermodynamics

Graphs below show the entropy versus energy $U$ of two systems $1$ and $2$ at constant volume. The initial energies of the systems are indicated by $U_{1, i}$ and $U_{2, i} ,$ respectively. Graphs are drawn to the same scale. The systems are then brought into thermal contact with each other. Assume that, at all times the combined energy of the two systems remains constant. Choose the most appropriate option indicating the energies of the two systems and the total entropy after they achieve the equilibrium.

The change in entropy when a $30 \mathrm{g}$ ice cube at $-12°\mathrm{C}$ is transformed into water at $100°\mathrm{C}$ $($in $\mathrm{J}/\mathrm{K})$ is

$($Take $\ell \mathrm{n}\left(\frac{273}{261}\right)=0.04; \ell \mathrm{n}\left(\frac{373}{273}\right)=0.312$, ${\mathrm{S}}_{\mathrm{ice}}=2100 \mathrm{J}/\mathrm{kg}-{}^{\circ }\mathrm{C},$$\left.{\mathrm{S}}_{\text{water}}=4200 \mathrm{J}/\mathrm{kg}-{}^{\circ }\mathrm{C}, {\mathrm{L}}_{\mathrm{f}}=3.33\times {10}^5 \mathrm{J}/\mathrm{kg}\right)$

The change in the entropy of a 1 mole of an ideal gas which went through an isothermal process from an initial state $(p_1,V_1,T)$ to the final state $\left(p_2,V_2,T\right)$is equal to

An ideal gas heat engine operates in Carnot cycle between $227^{\circ }\text{C}$ and $127^{\circ }\text{C}$ .It absorbs $6\times 10^4$ cal of heat at high temperature. Amount of heat converted to work is :

Work done by an engine is $({\mathrm{Q}}_1+{\mathrm{Q}}_2) \mathrm{J}$ when a heat engine absorbs ${\mathrm{Q}}_1$heat at ${\mathrm{T}}_1$ temperature and ${\mathrm{Q}}_2$ heat at ${\mathrm{T}}_2$ temperature.  This data:
