For a particular sample of an ideal gas, its energy depends solely on its
Options
- Avolume
- Btemperature
- Cpressure
- Ddensity
Correct answer
B. temperature
Step-by-step solution
For an ideal gas, there are no intermolecular forces of attraction. Hence, the potential energy of the gas molecules is zero. The internal energy of an ideal gas consists entirely of kinetic energy, which is directly proportional to its absolute temperature. The internal energy is given by U = f 2 n R T , where f is the degree of freedom, n is the number of moles, R is the universal gas constant, and T is the absolute temperature. For a particular sample of an ideal gas, n is constant. Therefore, its internal energ
