What makes ice melt faster control variables?
Independent Variables: The amount of salt, sugar, sand, water on the ice. Another is the different substances on the ice. Dependent Variable: The amount of water in each bowl after the experiment. The substance that makes ice melt the fastest is salt.
What is the dependent variable in melting ice?
The dependent variable is the time it takes the ice to melt. The control is the whole ice cube.
What factors affect the rate of melting ice?
Increase temperature (sun, fire, hot water, etc), pressure, decrease size, increase surface area, change chemistry/composition (salt), etc.
What element melts ice the fastest?
Calcium Chloride
Calcium Chloride Its ability to impose freezing point depression makes it an ideal material because it can accelerate the ice-melting process. The Peters Chemical Company says calcium chloride is its fastest ice-melting material.
What makes ice melt fastest research?
Salt reduces the freezing point of water, causing the ice to melt faster.
What makes ice melt fastest by Rebecca Hogan?
Conclusion: Salt and sugar both causes freezing point depression, therefore making the ice melt faster, however salt is more effective as salt dissolves into two components and creates more interference in preventing water from freezing.
What is the dependent variable in an experiment?
The dependent variable is the variable that is being measured or tested in an experiment. In a psychology experiment, researchers are looking at how changes in the independent variable cause changes in the dependent variable.
Did the flour cause the ice to melt faster?
Flour does not cause the ice cube to melt faster because the flour has almost the same freezing/melting point as pure water.
What makes ice melt faster conclusion?
Conclusions: Salt lowers the freezing/melting point of water/ice. When the salty ice cube was placed in the sun, the lower freezing point combined with continuous heat from the sun made the ice melt much faster.
How can you make ice melt faster without heat?
Salt is an effective deterrent to freezing down to 10 degrees Fahrenheit. Other compounds and chemicals can be used to melt ice. Calcium chloride, sodium chloride and laundry detergent are very effective. Bleach is reported to work the fastest when poured onto ice.
What makes ice melt fastest conclusion?
What makes ice melt?
When atoms break free, ice turns into liquid water. In other words, ice melts. If the supplied energy is even larger, then atoms completely move away from each other turning liquid water into water vapor.
