U, V, and T: Internal Energy, Specific Volume, and Temperature

In summary, internal energy is the total microscopic energy in a system, specific volume is the volume per unit mass of a substance, and the relationship between internal energy and temperature is directly proportional. As temperature increases, specific volume generally increases as well. The units of measurement for internal energy, specific volume, and temperature are joules or calories, cubic meters per kilogram, and degrees Celsius or Kelvin, respectively.

From that information, you can't. You want the find internal energy but all you know is specific volume, which is volume per unit mass, meaning you don't know the total mass.

If you did, however, you can find U by integrating Cv(T)dT from T=0 to current T.
 

Related to U, V, and T: Internal Energy, Specific Volume, and Temperature

1. What is internal energy?

Internal energy is the sum of all the microscopic energy in a system, including the kinetic and potential energy of its particles. It is a measure of the total energy contained within a system.

2. How is specific volume defined?

Specific volume is defined as the volume per unit mass of a substance. It is a measure of the amount of space occupied by a unit mass of a substance.

3. What is the relationship between internal energy and temperature?

Internal energy is directly proportional to temperature. As the temperature of a system increases, the internal energy also increases. However, the change in internal energy also depends on the specific heat capacity of the substance.

4. How does specific volume change with temperature?

Generally, as the temperature of a substance increases, its specific volume also increases. This is because the particles in the substance have more kinetic energy and are able to occupy more space.

5. What are the units of measurement for internal energy, specific volume, and temperature?

Internal energy is typically measured in joules (J) or calories (cal), specific volume in cubic meters per kilogram (m3/kg), and temperature in degrees Celsius (°C) or Kelvin (K).
