use the table to answer the question
1. the drop of food coloring spreads slowly
2. the drop of food coloring spreads very quickly
a student places a drop of food coloring into water samples. her observations are shown in the table. which statement best explains the observation in the table
the water molecules of sample 1 are transferring more kinetic energy
the temperature of sample 2 is close to freezing
the water molecules of sample 1 are moving faster
the temperature of sample 2 is higher
The statement "the water molecules of sample 1 are moving faster" best explains the observation in the table.
Based on the observations in the table, the best explanation for the slower spread of food coloring in sample 1 and the quicker spread in sample 2 is that the water molecules in sample 1 are moving faster.
To determine the best explanation for the observations in the table, let's analyze the information provided. The table shows that the drop of food coloring spreads slowly in one sample (sample 1) and very quickly in another sample (sample 2).
Based on these observations, we can eliminate the options related to temperature because the table does not provide any information about the temperature of the water samples. Therefore, the explanations related to the temperature of sample 2 being close to freezing or higher can be ruled out.
Now, let's consider the remaining options:
1. "The water molecules of sample 1 are transferring more kinetic energy."
2. "The water molecules of sample 1 are moving faster."
Both options suggest that the behavior of the water molecules in sample 1 contributes to the slow spread of the food coloring. However, the more accurate explanation is that the water molecules of sample 1 are moving faster.
When water molecules have more kinetic energy, they move faster and have a higher average speed. This increased speed of the water molecules in sample 1 would result in a slower spread of the food coloring because the water molecules would take longer to diffuse and mix with the colored dye.
Therefore, the best explanation for the observation in the table is that "the water molecules of sample 1 are moving faster."
