energy of gas particles.

I. Poking a hole in a tire.
II. Sticking an inflated balloon in a freezer.
III. Adding more air to a balloon.
IV. Lighting a candle.
V. Setting a block of ice on the dining room table.


A) IV and V
B) I and III
C) I, III, and V
D) II, III, and IV

Respuesta :

The answer to your question is B) I and III

Answer:The correct answer is option is B.

Explanation:

The kinetic energy of the gas molecule:

[tex]K=\frac{3\times R\times T}{2\times N_A}[/tex]

[tex]K\propto T[/tex]

The temperature of a gas is directly proportional to kinetic energy of the gas particles.

According to question actions which will have no effect on the kinetic  energy of gas particles ; poking a hole in a tire and adding more air to the a balloon will not effect the temperature of the gas molecule.

Where as action will result in change of the temperature of the gas particles which will change the kinetic energy of the gas particles.

So, action (I) and( III) will not the effect the kinetic energy of the gas particles. Hence,the correct answer is option is B.
