Glycol is a type of alcohol that can dissolve in water. When glycol is added to water, it lowers the freezing point and raises the boiling point of the solution. This property is useful in antifreeze solutions for cars and in heating systems to prevent freezing in cold temperatures. Glycol also helps to inhibit corrosion in metal pipes and equipment.

A solution of ethylene glycol would have the highest freezing point among the three options.
To find the molarity of the solution, you first need to calculate the mass of ethylene glycol in the solution. Then convert it to moles using the molar mass of ethylene glycol. Finally, calculate the molarity by dividing the moles of ethylene glycol by the volume of the solution in liters.
The presence of glycol in oil can improve the performance of machinery by enhancing lubrication and reducing friction. However, excessive glycol can lead to decreased viscosity and potential damage to machinery components, impacting longevity.
Polyethylene glycol can be effectively used to treat wood by penetrating the wood fibers and stabilizing them, preventing cracking and warping. It also helps to strengthen the wood and improve its overall durability.
No, antifreeze is not a colloid. Antifreeze is a liquid mixture of chemicals, typically ethylene glycol or propylene glycol, that is used to lower the freezing point of water in automobile cooling systems. Colloids are mixtures where particles are evenly dispersed in a continuous medium, like milk or fog.
