Question

for parts of the free - response question that require calculations, clearly show the method used and the steps involved in arriving at your answers. you must show your work to receive credit for your answer. examples and equations may be included in your answers where appropriate. a student is doing experiments with co₂(g). originally, a sample of the gas is in a rigid container at 299 k and 0.70 atm. the student increases the temperature of the co₂(g) in the container to 425 k. (a) describe the effect of raising the temperature on the motion of the co₂(g) molecules. note on your ap exam, you will handwrite your responses to free - response questions in a test booklet

Explanation:

According to the kinetic - molecular theory, as temperature increases, the average kinetic energy of gas molecules increases. For $CO_2(g)$ molecules, raising the temperature from 299 K to 425 K will cause the molecules to move faster and have more energetic collisions.

Answer:

The $CO_2(g)$ molecules will move faster and have more energetic collisions as the temperature is raised.
