increases

.

The speed of the molecules  

increases

.

The density of the fluid  

decreases

.

The fluid  

rises

.

Explanation:

this is correct on edge

Answer 2

When the temperature of a fluid increases, then the kinetic energy of the molecules INCREASES, the speed of the molecules INCREASES, the density of the fluid DECREASES, and the fluid RISES.

• Kinetic energy can be defined as motion energy, whereas potential energy is energy stored to be used when required.

• In a given object, as kinetic energy increases, the motion of the molecules also increases.

• An increase in kinetic energy (and temperature) in a fluid leads to the separation of its constituent particles, thereby decreasing the density.  

In conclusion, when the temperature of a fluid increases, then the kinetic energy of the molecules INCREASES, the speed of the molecules INCREASES, the density of the fluid DECREASES, and the fluid RISES.
