Question

click on the \energy\ button at the bottom of this simulation. add 4 pumps (200 particles) and start changing temperature (first by cooling to 0k and then heating). record atm to the closest ones place.

temperature (k)	average speed (m/s)	pressure (atm)
100
200
400

what is the effect of temperature on average speed of the particles?

• increasing the temperature increases the speed of the particles.
• increasing the temperature decreases the speed of the particles.
• increasing the temperature doesnt change the speed of the particles.

Explanation:

According to the kinetic theory of gases, temperature is related to the average kinetic energy of particles. Kinetic energy ($KE$) is given by $KE = \frac{1}{2}mv^{2}$, where $m$ is mass and $v$ is speed. As temperature (a measure of average kinetic energy) increases, the average speed of particles increases because higher temperature means more kinetic energy, and for a given mass, speed must increase to have more kinetic energy. So increasing temperature increases particle speed.

Answer:

A. Increasing the temperature increases the speed of the particles.
