Question

explain the characteristics of internal energy

Answer 1

Internal energy of the ideal gas. ... Therefore, internal energy changes in an ideal gas may be described solely by changes in its kinetic energy. Kinetic energy is simply the internal energy of the perfect gas and depends entirely on its pressure, volume and thermodynamic temperature.

Answer 2

$\bold{YOUR~ANSWER }$

$\bold{Characteristics~of~internal~energy}$

(a) The internal energy of a system is the extensive property.

(b) The internal energy is the state property.

(c) The change in internal energy does not depend on path by which the final state is reached.

(d) There will be no change in the internal energy in the cyclic process.

(e) The internal energy of the ideal gas is a function of temperature only.

(f) Internal energy of the system depends upon the quantity of the substance, its temperature, chemical nature, pressure and volume.

(g) The unit of E is ergs in CGS or joules in SI

1 Joule = ergs.
