Consider two flasks at 25 degree celsius, one contains an ideal gas and the other contains the real gas so3. which statement regarding these gases is true?
a. as the temperature approaches 0 k, the volume of the ideal gas will be larger than the volume of so3 because ideal gases lack inter-molecular forces.
b. as the temperature is decreased, the ideal gas will liquefy first because ideal gases have larger values of the van der waals coefficient b.
c. as the temperature approaches 0 k, the volume of the ideal gas will be smaller than the volume of so3 because ideal gases have larger values of the van der waals coefficient a.
d. after the temperature has been lowered about 100 k, the pressure of the ideal gas will be smaller than the pressure of so3 because the van der waals coefficient a for so3 is large.
e. after the temperature is increased about 100 k, the pressure of the ideal gas will be smaller than the pressure of so3 because the van der waals coefficient a for so3 is lar

Option (A) is the correct answer.

Explanation:

In real gases, there exists force of attraction between the molecules at low temperature and high pressure. This is because at low temperature there occurs a decrease in kinetic energy of gas molecules and high pressure causes the molecules to come closer to each other.

As a result, forces of attraction increases as molecules come closer to each other and therefore, gases deviate from an ideal gas behavior.

And, at low pressure and high temperature there exists no force of attraction or repulsion between the molecules of a gas because they have high kinetic energy. Hence, gases behave ideally at these conditions.

Thus, we can conclude that the statement as the temperature approaches 0 K, the volume of the ideal gas will be larger than the volume of because ideal gases lack inter-molecular forces, is true.

the ozone layer acts as a filter for the shorter wavelength and highly hazardous ultraviolet radiation (uvr) from the sun, protecting life on earth from its potentially harmful effects. when the sky is clear, there is an inverse relationship between stratospheric ozone and solar uvr measured at the earth's surface.
