Use the following table to answer the question:



The following samples are all water. Other than the temperature, all the water samples are identical. Which of the four samples has the lowest particle average kinetic energy?

a
1
b
2
c
3
d
4

1 answer

To determine which sample has the lowest particle average kinetic energy, we need to look at the temperature of each sample. According to the table, Sample 1 has the lowest temperature (20°C), which means its particles will have the lowest kinetic energy. Therefore, Sample a has the lowest particle average kinetic energy.
