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.
Question
Sayid recorded the temperatures of four substances in a chart.
A 2-column table with 4 rows. The first column labeled substance has entries W, X, Y, Z. The second column labeled Temperature (degrees Celsius) has entries 12, 18, 9, 20.
