What is a constant variable for the hypothesis:If ice melts in salt & fresh water, then it will melt faster in salt water.
|
|
The amount of salt
|
|
|
The melt Time
|
|
|
The fresh water.
|
|
|
The temperature of the water
|
Explanation:
Detailed explanation-1: -Salt water freezes at a lower temperature than the 32 degrees F at which freshwater freezes. The difference between the air temperature and the freezing point of salt water is bigger than the difference between the air temperature and the freezing point of freshwater. This makes the ice with salt on it melt faster.
Detailed explanation-2: -The time was the dependent variable because it was affected by the independent variable (salt). The average time for each type of basic salt was recorded. Kosher salt was the most efficient when melting the ice.
