Question

explain the sequence of events that happens when this fluid cools down. be sure to focus on what happen to the molecules and to the fluid in general . five event should be included in your answer

Answer 1

Sample Response: When the fluid cools, the kinetic energy of the molecules decreases. This causes the molecules to slow down and move closer together. Since the molecules are closer together, the density of the fluid increases and the fluid sinks.

Answer 2

Check below for the explanations required

Step-by-step explanation:

The following processes/events take place in the cooling of a fluid.

• A reduction in the kinetic energy of the molecules of the fluid
• The molecular speed reduces ( i.e.there will be a reduction in the speed at which the molecules move)
• The cohesive force between the molecules will increase ( i.e the molecules will no longer be drifted apart, they will now move closer to each other
• The temperature of the fluid reduces as it cools down
• There will be an increase in density
