Current Question (ID: 11088)

Question:

$\text{A sink, that is, the system where heat is rejected, is essential for the conversion of heat into work. From which law does the above inference follow?}$

Options:

1. $\text{Zeroth}$
2. $\text{First}$
3. $\text{Second}$ (Correct)
4. $\text{Third}$

Solution:

$\text{Hint: Recall the second law of thermodynamics.}$ $\text{Explanation: According to Kelvin-Planck's statement: No process is possible whose sole result is the absorption of heat from a reservoir and the complete conversion of the heat into work.}$ $\text{According to Clausius's statement: No process is possible whose sole result is the transfer of heat from a colder object to a hotter object.}$ $\text{This is known as the second law of thermodynamics.}$
