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.
The dependent variable is the rate of salt dissolution in the solution.
An ice cube melts faster in salt water.
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.
The independent variable in this experiment is the type of environment in which the ice cube is placed (air or water). This variable is manipulated by the experimenter to observe its effect on the rate of melting of the ice cube.
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.
salt water
hot water
yes.
yes
