Answer 1

Explanation:

The answer to the question is A

Answer 2

Answer:

The reason that antifreeze is added to a car radiator is (A) The freezing point is lowered and the boiling point is elevated.

Explanation:

• Antifreeze is the additive which helps in lowering of the freezing point of any water-based liquid.
• This antifreeze mixture is used for purpose of achieving the freezing-point for environments related to cold weather.

• Uses of Antifreeze:

1) They are used as a engine coolant that will help in regulating the temperature in the car.

2) It helps in holding the temperature of liquids upto 275 degree Fahrenheit.

The car should always be run by antifreeze coolant to prevent the damage of the engine.

The chemical name of the Antifreeze is Ethylene Glycol.

It is known as Ethylene glycol because the glycol is made up of ethylene.

It boils at temperature of 198°C.

Therefore, antifreeze is added to a car radiator and there is changes in The freezing point is lowered and the boiling point is elevated.
