Question 4(1 point) True or False: Cooler fluids sink to fill the space where the hot fluid once was. a True b False

## Step 1<br />The problem is a statement about the behavior of fluids in relation to temperature. The statement is: "Cooler fluids sink to fill the space where the hot fluid once was."<br /><br />## Step 2<br />To solve this problem, we need to understand the basic principles of fluid behavior. Generally, when a fluid is heated, it becomes less dense than the cooler fluid surrounding it. This is because the heat energy causes the molecules in the fluid to move faster and spread out, which decreases the density of the fluid.<br /><br />## Step 3<br />On the other hand, when a fluid is cooled, it becomes denser than the surrounding warmer fluid. This is because the cooling process causes the molecules in the fluid to slow down and come closer together, which increases the density of the fluid.<br /><br />## Step 4<br />Therefore, the statement "Cooler fluids sink to fill the space where the hot fluid once was" is not accurate. In fact, it's the opposite. Warmer fluids tend to rise, while cooler fluids sink.
