Question
Which of the following denotes the state of the system?
- Pressure
- Volume
- Temperature
- All of the above
Hint:
In thermodynamics, a state variable is an independent variable of a state function. Examples include internal energy, enthalpy, temperature, pressure, volume and entropy.
The correct answer is: All of the above
In the most commonly cited simple example, an ideal gas, the thermodynamic variables would be any three variables out of the following four: amount of substance, pressure, temperature, and volume. Thus, the thermodynamic state would range over a three-dimensional state space.

Pick the odd one out.
Density of substance is determined from the mass per unit volume. It is directly proportional to the mass of that substance. So this is the quality of a substance due to its mass.
Volume is the amount of space occupied by given a mass of a substance.
Temperature is the degree or intensity of the heat present in a substance or object, especially as expressed according to a comparative scale and shown by a thermometer or perceived by touch.
Pressure is an extensive property which depends on area of application of force.

In an open system, _______ can get into or out of the system.
In an open system, both mass and energy (heat and matter) can be transmitted. An open system can exchange both matter and energy that is present with its surroundings. The matter is easily exchanged between the open system and its surroundings. This can be simply described by adding or subtracting matter.
