**Q: **Is volume the quantity of three-dimensional space enclosed by a closed surface? ¶

**A: **Yes, for example, the space that a substance or shape occupies or contains.

**Q: **Is volume a concept important in thermodynamics where the volume of a working fluid is often an important parameter of a system being studied? ¶

**A: **Yes.

**Q: **Is volume a function of state and is interdependent with other thermodynamic properties such as pressure and temperature? ¶

**A: **Yes.

**Q: **Is volume related to the pressure and temperature of an ideal gas by the ideal gas law? ¶
