State, Path, Process, and Cycle
1 / 10
A steam power plant operates on:
Explanation: A steam power plant uses a cycle (e.g., Rankine cycle) where the working fluid undergoes repeated processes to produce work.
2 / 10
Which is true for a thermodynamic process?
Explanation: A process is a change from one state to another, e.g., expanding a gas from high to low pressure.
3 / 10
The path of a process determines:
Explanation: The path describes the sequence of states during a process, like whether it’s isothermal or adiabatic.
4 / 10
 In a thermodynamic cycle, the system:
Explanation: A cycle brings the system back to its starting state after a series of processes, e.g., in a heat engine.
5 / 10
An isothermal process involves:
Explanation: An isothermal process occurs at constant temperature, like compressing a gas while maintaining its temperature.
6 / 10
Which property is NOT used to define a state?
Explanation: State is defined by properties like temperature, pressure, and volume. Work is a path function, not a state property.
7 / 10
 Which of the following is an example of a cycle?
Explanation: A cycle involves processes that return the system to its initial state, like in a refrigeration system.
8 / 10
A thermodynamic process is:
Explanation: A process is a transition from one state to another, e.g., heating a gas to increase its pressure
9 / 10
The path in thermodynamics refers to:
Explanation: The path is the series of states a system goes through during a change, like isothermal compression of a gas.
10 / 10
 What defines a thermodynamic state?
Explanation: A state is defined by properties like temperature, pressure, and volume at a specific point, e.g., water at 25°C and 1 atm.
