Answer:
The amount of sugar that can dissolve in water increase .
Explanation:
- Energy, which is the capacity to do work or produce heat, affects the rate at which a solute will dissolve.
- Breaking up, crushing or grinding a sugar cube before adding it to water increases the sugar's surface area.
- The more surface area a solute has, the faster it will dissolve because more particles of the sugar can interact with the water.
- This means the finer the sugar particles, the faster it will dissolve.
- The sugar in the middle of a sugar cube is protected from the water by the sugar in the outer layers of the cube; the water has to go through those outer layers first.
- But if you crush the cube into a powder, all of the sugar is exposed to the water at once.

#6).
Every 1,000 mL makes 1 L
How many 1,000mL are there in 2,800 mL ?
That's division.
(2,800 mL) / (1,000 mL) = 2.8 L
#7).
The 'perimeter' means the 'distance all the way around'.
You have to know that both sides of a rectangle are the same length,
and also the top and bottom are the same length.
So the perimeter of this rectangle is
(2 yd) + (4.5 yd) + (2.yd) + (4.5 yd) = 13 yd .
Oops. The problem wants to know the perimeter in feet.
So you have to know that each yard is the same as 3 feet.
In order to find the number of feet in 13 yards, you have to
take 3 feet 13 times .
(3 feet) times (13) = 39 feet .
#8).
For this one, you have to know that every 36 inches makes 1 yard.
How many 36 inches are there in 48 inches ?
That's division.
(48 inches) / (36inches) = 1 and 1/2 yards .
#9).
For this problem, you have to know how to handle a mixed number,
and you also have to know that there are 16 ounces in 1 pound.
Add up the fruit:
(3-1/2 pounds) + (4 pounds) + 2 pounds) = 9-1/2 pounds
Now, remember that each pound is the same as 16 ounces. So if you
want to find the number of ounces in 9-1/2 pounds, you have to take
16 ounces 9-1/2 times .
(16 ounces) times (9-1/2) = 152 ounces.

#10).
This one is just adding up some numbers. But after you finish doing that, you have to know that 1,000 meters is called '1 kilometer' .
Add up the distances that Omar ran:
(1,000 meters) + (1,625 meters) + (1,500 meters) = 4,125 meters
The problem wants to know how many kilometers this is, so you have to figure out how many '1,000 meters' fit into 4,125 meters.
That's division.
(4,125 meters) / (1,000 meters) = 4.125 kilometers
