Question

The state of a gas can be described by quoting the relationship between ________.

• A. Pressure, volume, temperature, amount
• B. Pressure, volume, temperature
• C. Amount, volume, temperature
• D. Temperature, amount, pressure

Answer 1

The correct option is A Pressure, volume, temperature, amount

The state of a system is specified by state functions or state variables. The state of a thermodynamic system is described by its new variable or macroscopic (bulk) properties.

One can describe the state of a gas by quoting its pressure, temperature, volume and number of moles i.e., amount $(PV=nRT)$.
Hence, option $\left(D\right)$ is the correct answer.
