How does the surface area to volume ratio change as the cell size increases?
It decreases. As the dimensions increase by a number, the surface area increases by the same number to the power of 2, but the volume increases by the same number to the power of 3, meaning that the volume increases faster than the surface area.
When does an object have positive buoyancy?
A body has positive buoyancy when its density is lower than the density of the fluid the body is in.
What happens to the volume of an object when temperature decrease?
According to Charles law, the volume of gas decreases with lower temperatures and increases with higher temperatures
Is the surface temperature of white dwarf stars higher or lower than a red super giants?
Yes dwarf has higher temperature
What would happen if the volume of gas decreased and then increased?
The temp of the gas would first rise, then drop. If the final volume of the gas is lower than the volume at the start, the temp will be higher than at the start. If the final volume is greater than at the start, then the temp of the gas will be lower than at the start.
What is the relationship between density and buoyancy for objects and substances?
The higher the density the lower the buoyancy.
When the buoyant force on a submerged object is equal to the weight of the object how do the densities of the object and water compare?
Is is related through Archimedes principle, which states that the buoyancy force on an object is equal to the weight of liquid displaced by the submerged object. The weight of a volume of water is equal to the volume x density of water x the gravitational constant.FB = V ρ g
Is a lower surface area to volume ratio is more efficient for cellular activity?
Cellular activity often takes place at the interface between the cell and its surroundings - other cells or the environment. This area of activity is greater when the area to volume ratio is higher - not lower.

How are pitch and volume alike?
you can adjust them to b higher or lower
What is the force felt when an object is placed in water?
When an object is placed in water it experiences Buoyancy force. The magnitude of force is equal to the weight of water displaced and direction is perpendicular to free surface. Buoyancy is felt due to unequal amount of forces on upper and lower surface of object. Buoyancy force will not be felt in space.. This is not true, it can be felt if the water container is accelerating.
Let A and B be two solid spheres such that the surface area of B is 300 percent higher than the surface area of A The volume of A is found to be k percent lower than the volume of B The value of k is?
This is a very hard question but after various trials I have came up with an answer it is 40%
What are factors that affect gas pressure?
There are two factors that affect gas pressure. These factors are temperature and volume. Higher volume means lower pressure. Higher temperature means higher pressure.

When does an object have positive buoyancy?
A body has positive buoyancy when its density is lower than the density of the fluid the body is in.
How do you get your volume on your phone to work?
you use the die buttons to more the arrows up and down to make the volume higher and lower
Is the surface temperature of white dwarfs higher or lower than red super giants?
Yes dwarf has higher temperature
