Question
Which one is valid among the following statements about an ideal gas?(A) The vapor in a liquid-vapor mixture of water is always considered as an ideal gas.
(B) An ideal gas is an imaginary substance that has high intermolecular forces and each gas
molecule occupies a relative large volume.
(C) An ideal gas is an imaginary substance that is close to the real gas with very high density.
(D) The Pv=RT equation closely approximates the P-v-T behavior of the real gases at high
pressure and low temperature.
(E) The Pv=RT equation closely approximates the P-v-T behavior of the low-density real gases at
low pressure and high temperature.
Explanation / Answer
(E) The Pv=RT equation closely approximates the P-v-T behavior of the low-density real gases at low pressure and high temperature. ANSWER EXPLANATION an ideal gas is low density gas approaches absolute ideal behaviour with low pressure and high temp..
