You have dropped your popsicle and are watching it become a LIQUID. Which answer BEST explains what PHASE CHANGE has occurred AND how the molecule MOVEMENT has changed?

The PHASE CHANGE that has occurred is MELTNG and the molecule MOVEMENT has become FASTER.

The PHASE CHANGE that has occurred is CONDENSATION and the molecule MOVEMENT has become FASTER.

The PHASE CHANGE that has occurred is EVAPORATION and the molecule MOVEMENT has become SLOWER.

At higher temperatures:

particles in an object move faster

particles in an object have less energy

A cook had a jar containing a sweet food and a jar containing a sour food. The image above shows the sweet and sour foods. At room temperature, both foods are liquids. The same amount of energy was transferred out of both substances. Later, one of the foods had changed phase while the other had not. Which food changed phase, and how did it change?

The sweet food changed because the strong attraction between molecules made their movement slower. Its molecules now move in place.

The sweet food changed because the molecules were able to move fast enough to overcome the attraction between them. Its molecules now move away from each other.

The sour food changed because the weak attraction between molecules let them move faster. Its molecules now move away from each other.

The sour food changed because the molecules were able to move fast enough to overcome the attraction between them. Its molecules now move in place.
