Yes, in fact it doesnt melt. The salt goes through the ice, then make little holes in the ice.
If you are trying to measure how fast an ice cube melts with or without salt added, your Independent variable would be amount of salt added, and your Dependent variable would be the amount of time it takes to melt.
It would be the amount of time it takes to melt.
No.
An ice cube melts faster in salt water.
Salt water will melt an ice cube faster.
I dont know about the control but the independent variable is the amount of salt water and the dependent variable is the amount of water and salt rendered.
An "hypothesis" doesn't have independent and dependent variables until you design an experiment to test it. If you want to test the effect that salt in solution has on the freezing point of the solution, then the independent variable is the presence, absence, or concentration of the salt. The dependent variable is the freezing temperature you measure in each condition.
hot water
salt water
The independent variable! =] the dependent variable is what is changed by the independent variable... Eg... And a bad one at that lol... But the affect of salt on the boiling point of water... Salt is independent variable... Dependent is the boiling point =]
yes
yes.
