Answer:
For converting heat energy into work continuosly, a part of heat energy absorbed from the source has to be rejected. The heat energy can be rejected only if there is a body, whose temperature is less than that of the source. This body at lower temperature is the sink.

Question 6. Asked on :08 October 2020:05:39:07 PM
-Added by Shruti Srivastva Physics » Thermodynamics
Answer:
Heat and work are two different ways of transferring energy from one system to another. The the distinction between Heat and Work is important in the field of thermodynamics. Heat is the transfer of thermal energy between systems, while work is the transfer of mechanical energy between two systems.

Answer:
When liquid is converted into steam at its boling point, the temperature of liquid remains constant. i.e., change in temperature ΔT=0. Hence the specific heat, s=ΔQmΔT=ΔQm×0=∞

Question 31. Asked on :07 October 2020:05:49:19 PM
-Added by Shruti Srivastva Physics » Thermodynamics
Answer:
he first law of thermodynamics is a version of the law of conservation of energy, adapted for thermodynamic processes, distinguishing two kinds of transfer of energy, as heat and as thermodynamic work, and relating them to a function of a body's state, called Internal energy.
The law of conservation of energy states that the total energy of an isolated system is constant; energy can be transformed from one form to another, but can be neither created nor destroyed.
For a thermodynamic process without transfer of matter, the first law is often formulated[1][nb 1]
