Answer:
A, Hail is large spheres of ice and snow is small flakes of ice.
Under normal conditions, water freezes at 0 degrees Celsius or 32 degrees Fahrenheit. However by, adding salt, the water will cause the freezing point to become lower.
Half-life is the amount of time, in days or years( most common) a certain substance disintegrate half of it's content.
We are given the initial (Ao) and final (A) amount of the substance. The time passed (T) is also given and we are asked to find the half-life (t). We use the equation below:
A=Aoe^(-ln2/t)T
25=200e^(-ln2/t)(11.46)
Solve for t
Answer: 3.82 days
