Chapter 2, Problem 2.5NP

Interpretation Introduction

Interpretation:The height up to which a horse with mass 225 kg rise in 2.5 min needs to be determined if a single horse can heat 11.6 kg of the ice water from 273 K to 355 K in 2.5 h using a cannon boring machinery and the rate of work is same.

Concept Introduction: In thermodynamics, a reversible process can be defined as the process which can be reversed to its original state.

Hence in reversible processes, both the system and surroundings are returned to their initial states. In general all reversible processes are ideal processes and cannot occur naturally.

On the contrary, an irreversible process cannot come back to its initial condition. All spontaneous processes in nature are irreversible processes.

In an adiabatic process, the heat change is zero therefore the work done will be equal to the change in the internal energy.
