Question

For simple incompressible systems we need two intensive properties to define the state. Suppose you know the Temperature (T), mass (m), and volume (V) of a given system. How many additional properties are required to fix the state?

A.) 0
B.) 1
C.) 2
D.) 3

Answer 1

No additional properties are needed to define the state of a simple incompressible system if the Temperature (T), mass (m), and volume (V) are known. Mass can be related to density (an intensive property) when divided by volume.

Step-by-step explanation:

For a simple incompressible system, two intensive properties are required to completely define the state of the system. Since you have already been given the Temperature (T), mass (m), and volume (V) of the system, mass (m) being an extensive property, and temperature (T) being an intensive property, you do not need any additional property to fix the state because mass can be converted to density when you divide it by volume (an intensive property). Therefore, the answer is A.) 0 additional properties required to fix the state.
