Cars up north require more antifreeze than water as a result of the colder
temperature which makes the coolant in vehicles more prone to freezing.
<h3>What is Freezing point depression?</h3>
This is a situation which occurs when solutes are added to a solvent in
order to reduce the freezing point of the solvent. The impurities help lower
the freezing point of the solvent and is commonly used in vehicles.
This is because cars in the North are exposed to colder temperatures
which could freeze the coolant(solvent).

Answer:
cheaper foods are usually more processed and unhealthy, therefore, poorer people are likelier to be obese.
Explanation:
Answer:
The six changes are: Freezing: the substance changes from a liquid to a solid. Melting: the substance changes back from the solid to the liquid. Condensation: the substance changes from a gas to a liquid.
Assuming that the change of volumen was done at constant pressure and the quantity of gas did not change, you use Charles' Law of gases, which is valid for ideal gases:
V / T = constant => V1 / T1 = V2 / T2 => V1 = [V2 / T2] * T1.
Now plug in the numbers ,where T1 and T2 have to be in absolute scale.
T1 = 38.1 + 273.15 K = 311.25K
T2 = 15.0 + 273.15 K = 288.15K
V1 = 4.5L * 311.25K / 288.15 K = 4.86L.
