A student would like to determine the water content of an apple. What would be a possible hypothesis for this experiment?
If an apple is cut into 4 slices, than it will float on water.
If an apple is chopped in a food processor, then its mass will be 75 grams.
If an apple is placed in a refrigerator for 2 days, then its temperature will decrease.
If an apple is sliced and placed in salt water for 2 hours, then the mass of the apple will increase.
If an apple is weighed before and after being baked in an oven, then the water content will be 60%.
