Which sample has the lowest kinetic energy?

A. 1
B. 4
C. 2
D. 3

Answer :

To determine which water sample has the lowest kinetic energy, we need to look at their temperatures. The reason for this is that the kinetic energy of the molecules in a sample is directly related to its temperature. The higher the temperature, the higher the kinetic energy of the molecules, and vice versa.

Here is a step-by-step solution:

1. Review the Temperatures:
- Sample 1 has a temperature of 98.2°C.
- Sample 2 has a temperature of 46.0°C.
- Sample 3 has a temperature of 100.6°C.
- Sample 4 has a temperature of 31.4°C.

2. Identify the Lowest Temperature:
- Compare all the given temperatures:
- 98.2°C
- 46.0°C
- 100.6°C
- 31.4°C

- The lowest value among these temperatures is 31.4°C.

3. Determine the Corresponding Sample:
- The temperature of 31.4°C corresponds to Sample 4.

Thus, the sample with the lowest kinetic energy is Sample 4.
