How does the surface area of a cube change if the length of each side is doubled?
The surface area is quadrupled.
What is a chunk?
a chunk is a group of related commands grouped under one area
How does cell's ratio of surface area to volume change as the cell grows larger?
because it has the surface area of volume
Does the surface area change in the same proportion?
Yes.
Do the round shape of blood cells gives them extra surface area?
yes because it is like any other object if you change the shape you change the surface area
How does surface area of the zinc affect its speed of reaction with sulfuric acid?
The surface is where the reaction takes place. The more surface is exposed, the faster the reaction will proceed. Compared to a chunk of zinc, the same mass of zinc powder can react nearly instantaneously.
How could you calculate the surface area of a shape?
To calculate the surface area of a shape find the area of each side, and then, add all of the areas together. The sum of the areas is the surface area.
How does surface area different from area?
Surface area is the area of all the sides of a 3D object, but area could be anything. e.g. Area is the surface of a 2D object or if you say the area of all the sides, it means the same as Surface area. -----=-----=-----=-----=-----=-----=-----=-----=-----=-----=-----=-----=-----=-----= By Austin from Covenant Christian School
Why are volume and surface area alike?
Think of surface area as your skin and volume as all the contents inside your body. So they relate because surface area can hold volume or volume could be inside the surface area.
How does a cell's ratio of surface area to volume change as the cell grows larger?
As the cell grows larger the ratio of surface area to volume increases. Larger cell = more volume for the amount surface area.
How will the pressure of an object change if area is doubled?
It won't. The pressure within a hollow object may change if the surface area changes, hence the volume. The total pressure acting on the exterior of a solid object may change if the total surface area changes.
