The kinetic energy of a substance is directly proportional to its temperature. Therefore, the water sample with the lowest temperature will have the lowest kinetic energy.
Looking at the table, we can see that sample 1 has a temperature of 20°C, sample 2 has a temperature of 25°C, sample 3 has a temperature of 30°C, and sample 4 has a temperature of 35°C.
Therefore, the water sample with the lowest kinetic energy is sample 1.
Thus, the answer is C. 1.
A student records the temperature of several water samples as shown in the table. Other than the temperature, the water samples are the same. which sample has the lowest kinetic energy?
