Question

Argon gas has a boiling point of -197 °C. Which of the following diagrams best represents the

distribution of argon atoms in a steel sphere at -190 °C?

Answer 1

(a)

Step-by-step explanation:

Hello,

In this case, the temperature required to boil argon, it means, transform it from liquid to gas is -197 °C. In such a way, since the temperature inside the steel sphere is -190 °C, which is greater than the boiling point, we realize argon is gaseous, therefore, the molecules will be spread inside the sphere as they will be moving based on the kinetic theory of gases.

For that reason, answer is scheme (a).

Best regards.
