It would be 1.5 per foot, but how many feet do they want
Answer:
iodide produces fumes when heated - sublimation
An iceberg turns to ocean water - melting
Candle wax turns to liquid when hot - melting
"Fog" is created from dry ice - sublimation
Step-by-step explanation:
Melting is the substance changing from a solid to a liquid.
Sublimation is when a substance changes directly from a solid to a gas without a liquid phase.
To find the area to be surrounded by a gravel path, we need to calculate two areas. First, the area of the whole space and, second, the area of the pond. We subtract these values to obtain the actual area for the gravel path.
A(whole space) = pi x (250)^2 = 62500π ft^2
A(pond) = pi x 200^2 = 40000π ft^2
Actual Area = 62500π ft^2 - 40000π ft^2 = 70686 ft^2 ----> OPTION A
