1 The second law of thermodynamics disallows some processes consistent with the first law of thermodynamics
2 Spontaneous processes are reversible
3 In isothermal quasi static processes, the heat cannot be absorbed or given out by the system.
4 In quasi-static processes, the pressure and temperature of the environment can differ from those of the system significantly.
Explanation:
A Correct statement as follows, (i) The second law of thermodynamics disallows some processes consistent with the first law of thermodynamics. (ii) $2^{\text {nd }}$ law of thermodynamics states that all spontaneous process are irreversible. (iii) In isothermal quasi-static process, the heat can be absorbed or given out by the system. (iv) In quasi-static process the system will be in equilibrium with the surroundings at every stage. Hence, in quasi-static process the pressure and temperature of the environment can not differ from those of the system significantly.

Heating of water at atmospheric pressure to covered under the thermodynamic process known as
1 isobaric
2 isochoric
3 isoentropic
4 isothermal
Explanation:
A Heating of water at atmospheric pressure to covered under the thermodynamic process known as isobaric process because as heating of water is done at uniform pressure through out the heating process: $\mathrm{Q}_{\mathrm{R}}=$ Heat rejected $\mathrm{Q}_{\mathrm{S}}=$ Heat supply

Which of the following is not true about the process?
1 For isothermal process, $\mathrm{dT}=0$
2 For isobaric process, $\quad \mathrm{dP}=0$
3 For isochoric process, $\mathrm{dE}=0$
4 For adiabatic process, $d Q=0$
Explanation:
C For an isothermal process temperature remains constant, therefore, $\mathrm{dT}=0$. For an isobaric process pressure remains constant, therefore, $\mathrm{dP}=0$. For an adiabatic process, there is no exchange of heat between system and the surrounding, therefore, $\mathrm{dQ}=0$. Volume will be constant in isochoric process.
