In this quiz, you will design an experiment about melting ice. Read the following questions an 8th grade scientist made about ice and
identify the best hypothesis for this experiment.
Why does the ice on the roads melt faster when salt is spread on them?
The best hypothesis is:
If salt is spread on the roads, then it turns
into heat and melts the ice faster.
If salt touches ice, then the ice runs away
because it's scared, melting faster.
If salt is spread on the roads, then the ice
melts faster because the salt lowers the
freezing point of water.
If salt is spread on the roads, then the ice.
melts faster because it's magic.

Final answer:

The hypothesis that salt lowers the freezing point of water and makes ice melt faster is the best explanation for why salt helps melt ice on roads.


Explanation:

Hypothesis: If salt is spread on the roads, then the ice melts faster because the salt lowers the freezing point of water.

Explanation: When salt is applied to ice, it disrupts the ice's ability to stay solid by lowering the freezing point of water. This causes the ice to melt at a lower temperature than it normally would.

Importance: Understanding how salt affects the freezing point of water is crucial for various applications, such as de-icing roads in winter to ensure safe driving conditions.
