The temperature of a quantity of an ideal gas is
A) one measure of its ability to transfer thermal energy to another body.
B) proportional to the average molecular kinetic energy of the molecules.
C) proportional to the internal energy of the gas.
D) correctly described by all the statements above.
E) correctly described only by (a) and (b) above.

Question

Quizplus · Accepted Answer

All statements correctly describe aspects of the temperature of an ideal gas. Temperature is indeed a measure of a body's ability to transfer thermal energy (A), it is proportional to the average molecular kinetic energy of the molecules in the gas (B), and it is also proportional to the internal energy of the gas (C), especially in the context of ideal gases where the internal energy is primarily kinetic.
