Answer: The correct answer is The particles in substance W have a lower average kinetic energy than the particles in substance X.

Step-by-step explanation:

The temperature of substance W is 12 degrees Celcius, whereas substance X is 18 degrees Celcius. Therefore, substance X has more kinetic energy than substance W and this answer choice is correct. This answer was also confirmed correct on the test.

The best supported by the data particles in substance Z have a lower average kinetic energy than the particles in substance Y. Therefore, The particles in substance Z have a lower average kinetic energy than the particles in substance Y is correct .

The average kinetic energy of particles is directly related to the temperature of a substance.

The higher the temperature, the greater the average kinetic energy of the particles.

In the given data:

Substance W has a temperature of 12 degrees Celsius.

Substance X has a temperature of 18 degrees Celsius.

Substance Y has a temperature of 9 degrees Celsius.

Substance Z has a temperature of 20 degrees Celsius.

Comparing the temperatures:

Substance W (12°C) has a lower temperature than Substance X (18°C).

Substance Y (9°C) has a lower temperature than Substance W (12°C).

Substance Z (20°C) has a higher temperature than all the other substances.

Therefore, we can conclude that the particles in Substance Z have a greater average kinetic energy than the particles in Substance W, X , and Y.

So, the conclusion "The particles in substance Z have a lower average kinetic energy than the particles in substance Y" is not supported by the data.

The correct conclusion is: The particles in Substance Z have a greater average kinetic energy than the particles in Substance Y.
