How do you increase the surface area withour increasing the volume?
The smallest surface area for a given volume is a sphere. A spherical object such as a balloon represents the minimum energy required to maintain the volume of the material within. A balloon filled with water if stretched will increase the surface area of the balloon without altering the volume as water is non-compressible. Any alternative shape that encloses the same volume will have a larger surface area than a sphere. A perfect example is a drop of liquid in a zero gravity environment which will vibrate when intially created but will gradually slow to a stop and take the form of a perfect sphere.
What increases the surface area of the cerebral?
The surface area of the cerebral cortex is increased by its folding into gyri and sulci. This folding allows for more neurons to be packed into a smaller space, increasing the brain's processing power without significantly increasing its size.
When sugar is disolved in water there is increasing in the volume?
The volume increase.
Why is a cell forced to divide?
it's the problem of surface area -to- volume ratio that mean there is no fitting between increasing of surface area and increasing of volume
What is the result of increasing the temp of a gas?
The kinetic energy will increase

What happens to the surface area and volume of a cell as it becomes larger?
They both increase with increasing cell radius (if we model a cell as a sphere). However, the rate of increase of the surface area is in general slower (dA/dr = 8πr) compared to the rate of increase of the volume (dV/dr = 4πr2). This would mean that with increasing cell size, the surface area to volume ratio is becoming smaller and smaller, giving a cell less surface area for the transport of nutrients for a given unit volume.

What happens when you increase volume without increasing mass?
Increasing volume without increasing mass usually means the object becomes less dense. This can happen by adding air or expanding the space the object occupies. The mass remains the same, but the density decreases.
If you increase an objects mass but not its volume what changes?
Increasing an object's mass without changing its volume will cause its density to increase. Since density is mass divided by volume, with volume remaining constant, any increase in mass will result in a higher density.

Why will increasing a rocket's volume increase altitude?
Magnets.
What happens when temperature of gas is increasing?
The volume will increase
If you increase an objects mass but not its volume what have you changed?
You have changed the object's density by increasing its mass without changing its volume. Density is calculated by dividing mass by volume, so as mass increases while volume remains constant, the density of the object will also increase.
When volume increases does mass increase?
This is not entirely true. The mass will only increase with volume if you are adding more to to increase the volume. However, you can increase the volume without increasing mass. An example of this would be heating something. As you heat things the molecules want to move about more, as this happens they spread further and further apart. This is easiest to observe in when things are in a gaseous state. You can determine how the volume of a gas changes by PV=nRT; where P is pressure, V is volume, n is he number particles, R is constant, and T is the temperature in Kelvin.
