I have an assignment. It has two boxes to model the particles of the same gas at different temperature (18 and 45 degrees Celsius). I have to write two or three sentences relating the temperature, the average kinetic energy, and the motion of the particles in the two boxes.

This is were I started.

The first area has the temperature of 18 degrees Celsius while the second has the temperature of 45 degrees Celsius. SInce the temperature is higher in the second area, the particles in the second area move faster. This higher velocity makes he average kinetic energy higher in the second area.

How is my response.

I would say so far so good. You might want to mention something about KE = 1/2 mv^2

Hows this:

The first area has the temperature of 18 degrees Celsius while the second area has the temperature of 45 degrees Celsius. It is proven that thermal energy is connected with kinetic energy. In other words, the higher temperature of the second area shows us that the second area had a higher level of kinetic energy. Additionally, kinetic energy is also related to the movement of the particles of gas as seen in the formula KE = 1/2 mv^2 (where KE is kinetic energy, m is mass, and v is velocity).

That sounds good. Remember that anytime you use a formula you should define the terms. Therefore, I would writae KE = 1/2 mv^2 where KE is kinetic energy in joules, m is mass in kg, and v is velocity of the particles in m/s.

Your response is well-written and provides a clear explanation of the relationship between temperature, average kinetic energy, and the motion of particles in the two boxes. You accurately state that particles in the second area (with a temperature of 45 degrees Celsius) move faster due to the higher temperature. This increased velocity leads to a higher average kinetic energy in the second area compared to the first area (with a temperature of 18 degrees Celsius). Overall, your response effectively relates the concepts of temperature, average kinetic energy, and particle motion in a concise manner.
