In cold countries, ethylene glycol is added to water in radiators of cars during winters. Why?

In a cold climate water gets forzen causing damage to the radiator of a car. Ethylene glycol is used as an antifreezing agent for the purpose. Calculate the amount of ehtylene glycol to be added to 4kg of water to prevent it from freezing at -6^@C ( K_f for water = 1.85 K mol^(-1) kg)

Why does the air pressure in a car tyre increase during driving?

Why velocity of hot water is greater than velocity of cold water.

While diluting an acid, why is it recommended that the acid should be added to water and not water to the acid?

Explain why Air pressure in a car tyre increases during driving.

An antifreeze solution is prepared from 222.6 g of ethylene glycol (C_2H_6O_2) and 200 g of water. Calculate the molality of the solution. If the density of the solution is 1.072 g mL^-1 , then what shall be the molarity of the solution?

Ethylene glycol (molar mass = 62gmol^-1) is a common automobile antifreeze. Calculate the freezing point of a solution containing 12.4g of this substance in 100g of water. Would it be advisable to keep this susbtance in the car radiators during summer? Given K_f for water = 1.86 K kg//mol K_b for water = 0.612 K kg//mol

Explain why Aquatic species are more comfortable in cold water rather than in warm water.

Determined the molarity of an antifreeze solution containing 250g water mixed with 222g ethylene glycol (C_2H_6O_2) . The density of this solution is 1.07g mol^-1 .

Decrease in vapour pressure of water by adding 5 mol sucrose or 5 mol urea to one kg of water is same why?
