What does ethylene glycol do to the solution in a vehicle's radiator?

Ethylene Glycol is used as in Vehicle's Radiators due to following reasons;

1) Lower freezing Point:
                                      The freezing point of Ethylene Glycol is -12.9 °C. When added with water it decreases the freezing point of water from 0 °C. Hence, water in radiator will not freeze in winter when temperature drops below 0 °C.

2) Higher Boiling Point:
                                    Boiling Point of Ethylene Glycol is 197.3 °C. So solution of Ethylene Glycol in radiator will prohibit vapor formation and decreases issues related to vapors in internal system of vehicle.

3) Higher Specific Heat Capacity:
                                                     Due to high heat capacity it quickly absorbs heat generated in engine and keeps it cool with high rate.

The answer is C it raises the boiling point and lowers the freezing point

Work done = force ×distancebut force = mass ×gravityand gravity = 10m\s force = 2×10 = 20 work done = 20×3 = 60 joules

It would be (at) + cu (s)
