FAQs on GATE Past Year Questions: Properties of Pure Substances - Thermodynamics - Mechanical Engineering
| 1. What are the properties of pure substances in mechanical engineering? |  |
Ans. Properties of pure substances in mechanical engineering refer to the characteristics that define the behavior of substances, such as water or refrigerants, under various conditions. These properties include specific volume, specific enthalpy, specific entropy, specific internal energy, and temperature.
| 2. How is specific volume defined for pure substances in mechanical engineering? | |
Ans. Specific volume is the ratio of the volume of a substance to its mass. In mechanical engineering, it is expressed as the volume occupied by one unit mass of a substance. It is denoted by the symbol "v" and is typically measured in cubic meters per kilogram (m^3/kg).
| 3. What is the significance of specific enthalpy in the study of pure substances in mechanical engineering? | |
Ans. Specific enthalpy is a property that represents the energy content of a unit mass of a substance. It accounts for both the internal energy and the flow work associated with the substance. In mechanical engineering, specific enthalpy is particularly important in thermodynamic analysis, as it helps determine the amount of heat transfer or work done during a process.
| 4. How is specific entropy useful in the analysis of pure substances in mechanical engineering? | |
Ans. Specific entropy is a property that measures the level of disorder or randomness in a unit mass of a substance. It provides insights into the changes in the entropy of a substance during processes such as heat transfer or phase transitions. In mechanical engineering, specific entropy plays a crucial role in determining the efficiency of thermodynamic systems and the irreversibility of processes.
| 5. Why is temperature considered a key property of pure substances in mechanical engineering? | |
Ans. Temperature is a fundamental property that characterizes the thermal state of a substance. In mechanical engineering, it is vital for analyzing and predicting the behavior of pure substances in various thermodynamic processes. Temperature influences the direction and rate of heat transfer, as well as the phase changes and equilibrium conditions of substances. It serves as a basis for designing efficient heat exchange systems and understanding the thermal performance of mechanical devices.
