Temperature and volume in an experiment are part of?
- A
Surroundings
- B
System
- C
State of a system
- D
All of these
A thermodynamic state of a system is defined by specifying values of a set of measurable properties sufficient to determine all other properties. For fluid systems, typical properties are pressure, volume and temperature. So option C is correct.
Everything except the system is called its surroundings. It includes the external environment only. Hence, this option is incorrect.
System is the part that is under observation. Temperature and volume are not included in the system, hence, this option is also incorrect.
State of a system refers to its conditions at the moment of observation, for example, its temperature, pressure, volume, etc. As temperature and volume are a part of state of the system, this option is the correct option.
As only option C is correct, this option is incorrect.
