Explain why the temperature of water might increase when a solution forms
Setler79 [48]
That is because the water would be the solvent, therefore, something is dissolved into it making it a solution. The solute increase the temperature of the solvent (water).

<span> The temperature of the water in both beakers is greater than 8 °C
This is because since the water passes on heat to the spheres, that means they are at a higher temperature then the spheres. if they were at a lower temp. The spheres would pass on heat to the water.

Anh measured the temperature of a pond near his house. Before he left for school, the water in the pond was 18 degrees celsius.
Hitman42 [59]

As the temperature increases, B) the molecules started moving faster.

Explanation:

The temperature of a substance is a measure of the average kinetic energy of the particles in a substance. In particular, it can be found that the temperature is directly proportional to the average kinetic energy of the particles:

T\propto KE

The kinetic energy of a particle is given by

KE=\frac{1}{2}mv^2

where

m is the mass of the particle

v is its speed

This means that the higher the temperature of a substance, the greater the speed of the particles in the substance.

Therefore, if we apply this concept to this problem, we infer that as the temperature of the water in the pond gets higher, the speed of the molecules inside the water increases, which means that the molecules are moving faster.

Therefore, the correct answer is

B) the molecules started moving faster.
