Explanation:
Boiling-point elevation describes the phenomenon that the boiling point of a liquid (a solvent) will be higher when another compound is added, meaning that a solution has a higher boiling point than a pure solvent. This happens whenever a non-volatile solute, such as a salt, is added to a pure solvent, such as water.

Complete question is;
Which of the following object would take you the greatest amount of force to accelerate.
A) a soccer ball with a mass of 0.5 kg
B) a refrigerator with a mass of 200 kg, C) a bike with a mass of 25 kg
D) a car with a mass of 5,000 kg,
Answer:
D) a car with a mass of 5,000 kg
Explanation:
Formula for force is;
F = ma
Where;
F is force
m is mass
a is acceleration
Now, Force is directly proportional to the acceleration and mass.
Thus, the higher the mass, the greater the force.
Thus, the object that will require the most force is the one that has the highest mass.
Looking at the options, the one with the highest mass is option D.
