Question 7 • Chemistry

Which sequence represents the relationship between temperature and volume as explained by the kinetic-molecular theory?

Answer
A
higher temperature right arrow more kinetic energy right arrow less space between particles right arrow lower volume
B
higher temperature right arrow less kinetic energy right arrow more space between particles right arrow lower volume
C
higher temperature right arrow more kinetic energy right arrow more space between particles right arrow higher volume
D
higher temperature right arrow less kinetic energy right arrow less space between particles right arrow higher volume

Explanation

According to the kinetic-molecular theory, increasing temperature gives particles more average kinetic energy. They move faster and spread farther apart, so the gas occupies more volume when pressure is held constant. Therefore, the sequence in choice C—higher temperature, more kinetic energy, more space between particles, and higher volume—is correct.
