Question

A student places a drop of food coloring into two water samples. Her observations are shown in the table. Which statement best explains the observations in the table?

Answer 1

The statement that best explains the observations in the table is that The water Molecules of sample 1 are moving faster.

How does the temperature influence the molecules of water?

Note that an increase in temperature is one that can make the water molecules to have more energy and therefore move a lot.

When this happens the water molecules are said to move far apart and there will be an increase in the volume of water.

Note also that  as water is heated, it therefore expands or simply say it increases in volume and it said to be less dense.

The Sample Observation and full question  is given below

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 two water samples. Her observations are shown in the table. Which statement best explains the observations in the table?

• The water molecules of sample 1 are transferring more kinetic energy.
• The water molecules of sample 1 are moving faster.
• The temperature of sample 2 is close to freezing.
• The temperature of sample 2 is higher.
