Why is it advised to add ethylene glycol to water in a car radiator while driving in a hill station.

Ethylene glycol is added to water as an antifreeze. It will

Why it is not advised to wear polyester clothes while working in a kitchen?

A 0.5 molal solution of ethylene glycol water is used as coolant in a car. If the freezing point constant of water be 1.86^(@)C per mole, the mixture shall freeze at

Properties such as boiling point, freezing point and vapour pressure of a pure solvent change when solute molecules are added to get a homogeneous solution. These are called colligative properties. Applications of colligative properties are very useful in day-to-day life One of its examples is the use of ethylene glycol and water mixture as an anti-freezing liquid in the radiator of automobiles.A solution M is prepared by mixing ethanol and water. The mole fraction of ethanol in the mixture is 0.9.Given: Freezing point depression constant of water (Kfwater​)=1.86Kkgmol−1Freezing point depression constant of ethanol(Kfethanol​)=2.0Kkgmol−1 Boiling point elevation constant of water(Kbwater​)=0.52Kkgmol−1 Boiling point elevation constant of ethanol (Kbethanol​)=1.2Kkgmol−1 Standard freezing point of water =273K Standard freezing point of ethanol =155.7K Standard boiling point of water =373K Standard boiling point of ethanol =351.5K Vapour pressure of pure water =32.8mmHg Vapour pressure of pure ethanol =40mmHg Molecular weight of water =18gmol−1 Molecular weight of ethanol =46gmol−1 In answering the following questions, consider the solutions to be ideal dilute solutions and solutes to be non-volatile and non-dissociative. Water is added to the solution M such that the mole faraction of water in the solution becomes 0.9. the boiling point of this solution is

In cold concentries, a solution of water and ethylene glycol is used as coolant in an automobile engine radiator instead of water. Explain

STATEMENT - 1 : addition of ethylene glycol to water lowers the freezing point of water, therefore, used as antifreeze substance. STATEMENT - 2 : Ethylene glycol is soluble in water.

The temperature of a city was found to be -9.3^(@) C. A car used, whose rasiator was filled with 5 L of water . What minimum quantity of antifreezing agent ethylene glycol were added to water of raiator in order to use the car for teavelling? ( K_(f) of water 1.86 k mol^(-1))
