Several interesting observations from the world around you are listed below. Which of these is NOT explained by a colligative property?

1.) At high altitude it takes longer to cook spaghetti.

2.) The freezing point of water is lowered when salt is added.

3.) A lobster will die when placed in fresh water.

4.) Water boils at a higher temperature when salt is added.

5.) Antifreeze is added to a car radiator to keep the car from overheating.

1.) At high altitude it takes longer to cook spaghetti.

Explanation:

The first even describes depression in boiling point due to reduction in external pressure . It is not a colligative property.

Depression of freezing  point and elevation of boiling point due to impurity or addition of solute are colligative priperty.

for step 7 table c on the lab "newtons law of action"   the average time it took the car to travel .25 meters   was 1.92 seconds.

the average time it took the car to travel 0.50 meters was 2.61 seconds

hope this : )

he uptake of drugs from the intestine is often strongly influenced by diffusion. for example, consider a water-insoluble steroid for treating inflammation that is solubilized in aggregates of detergent molecules, called micelles. these micelles, aggregates of 80 soap molecules, have a molecular weight of 24,000, a diameter of 2.6 nm, and a charge of -27. the positively charge ions (counterions) in this system are na".
