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  $6.0\hspace{0.17em}\mathrm{kJ}\hspace{0.17em}{\mathrm{mol}}^{-1}\mathrm{\hspace{0.17em}}\mathrm{at}\mathrm{\hspace{0.17em}}0°\mathrm{C}$)

The second law of thermodynamics may be written is used symbols as-

The heat taken from a sink is heated on-

The _____ of the thermodynamics states that, no process is possibel whose sole results is the absorption heat from a reservation and the complete conversion of heat into work.

_________ of thermodynamics is used for understanding the concept of entropy change.

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.

Clausius's statement is a part of

A refrigerator operates on:

What do you mean by Clausius's statement?

Heat engine is a device in which a system undergoes a _____ process resulting in conversion of heat into work. (cyclic/non-cyclic)

_____ in thermodynamics refers to the situation when macroscopic variables describing the thermodynamic state of a system do not depend on time.

Which of the following statements is true? The entropy of the universe

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

Combustion of sucrose is used by aerobic organisms for providing energy for the life sustaining processes. If all the capturing of energy form the reaction is done through electrical process (non P-V work) then calculate maximum available energy which can be captured by combustion of 34.2 gm of sucrose

Given : $\Delta {\text{H}}_{\text{combustion}}\left(\text{sucrose}\right)=-{\text{6000 kJ mol}}^{-1}$

$\Delta {\text{S}}_{\text{combustion}}=\text{180 J/K-mol}$ and body temperature is $300 \mathrm{K}$
